two forces of magnitude 3N and 7N respectively act on body. What are the maximum and minimum resultant forces that act on the body?
1. two forces of magnitude 3N and 7N respectively act on body. What are the maximum and minimum resultant forces that act on the body?
Jawaban:
Max = 10 N
Min = 4 N
Penjelasan:
If there are two force act on the same body, the value will be maximum if both of them in same direction so we can add to calculate. Otherwise if one another isn't in same direction, it will be minimum (because we can subtract the big one with the little one)
2. Two pieces of each force vector F1 and F2=10N =10N to form an angle of 60° as shown below. Resultant vector is...
given :
F1 = 10 N
F2 = 10 N
α = 60
asked:
R = ?
answer :
R² = F1² + F2² + 2 F1 F2 cos 60
R² = 10² + 10² + 2x10x10x1/2
R² = 100 + 100 + 100
R² = 300
R = √300
R = 10√3 N
3. Two pieces of each force vector F1 and F2=10N =10N to form an angle of 60° as shown below. Resultant vector is...
R = √f1² + f2² + 2.f1.f2 x cos60
R = √100 + 100 + 200 x 1/2
R = √200 + 100
R = √300
R = 10√3 N
4. If the mass of the box = 4 kg, F1 = 10 N, and F2 = 2 N, then the magnitude and direction of the acceleration of the box is
Jawaban:
Magnitude: 4 m/s² Direction: towards the left (due to F1 being greater than F2)
Answer:
Acceleration of the box is 8 N.
Solution:
The magnitude and direction of the acceleration of the box can be calculated using Newton's Second Law, which states that the net force (Fnet) acting on an object is equal to the mass of the object (m) multiplied by its acceleration (a):
Fnet = ma
In this problem, the mass of the box is given as 4 kg. The forces F1 and F2 are given as 10 N and 2 N, respectively. Therefore, the net force is Fnet = 10 N - 2 N = 8 N.
Substituting the given values into Newton's Second Law, we have:
Fnet = ma
8 N = (4 kg)(a)
Solving for a, we have:
a = 8 N / (4 kg) = 2 m/s2
Therefore, the magnitude of the acceleration of the box is 2 m/s2 and the direction of the acceleration is in the same direction as the net force, which is 8 N.

7. tolong bantu jawab plissssssss kakk cukup caranya ajaaaaaa plisssssssTwo charge each of +90 µC and+40 μC are separated 20 cm. Thelocation of the third charge+2 μC from the first change so thatthe resultant of the force on thischange is zero is....
Jawaban:
q1 = 90μC
q2 = 40μC
q3 = 2μC
d = 20cm = 0.2m
Let d1 = x
d2 = 0.2 - x
ΣF = 0
F1 - F2 = 0
F1 = F2
[tex] \frac{k \times q1 \times q3}{(d1)^{2} } = \frac{k \times q2 \times q3}{(d2)^{2} } [/tex]
[tex] \frac{q1}{ {(d1)}^{2} } = \frac{q2}{ {(d2)}^{2} } [/tex]
q1(d2)² = q2(d1)²
90μ(0.2-x)² = 40μ(x)²
9(0.2-x)² = 4x²
3(0.2-x) = 2x
0.6 - 3x = 2x
x = 0.6 ÷ 5
= 0.12 m
= 12 cm

F = 100 ke arah kanan
karena F1 masih ada sisa sehingga membuat meja terdorong ke kanan dikarenakan Ryan mendorong meja tersebut ke kanan sebesar 300 Newton.
13. Find the total work done by forces A and B if the object undergoes the displacement C. Hint : can you add the two forces first? Ini peljrn vektor

Sigma means kumpulan, kalo bhs indonesia resultan gaya, atau jumlah gaya. Jadi gayanya dijumlahkan dulu terus dikali perpindahan.

18. 11.The resultant of two vectors with the same magnitude of F is √3. What is the angle formed by the two vectors? A. 0 0 B. 300 C. 450 D. 600 E. 900
Penjelasan:
Given :
The resultant of two vectors with the same magnitude of F is √3.
What is the angle formed by the two vectors?
The solutions:
let F1 = F2 = F
so, the equation is :
R² = F²+F²+2(F)(F).cos angle
(√3F)² = 2F² + 2F².cos angle
3F² = 2F² + 2F².cos angle
3F²-2F² = 2F².cos angle
F² = 2F².cos angle
cos angle = F²/2F²
cos angle = ½
the angle formed by the two vectors = cos`¹ ½
= 60°(optionD)

A circular loop L₁ with a radius of 7 cm carries a current of 12 A and another circular loop L₂ with a radius of 1.6 cm, has 30 turns and a current of 3A is placed at the center of the circle L₁. The resultant magnetic field at point P if two currents flow in opposite directions is equal to [tex]2,305\pi \times 10^{-3}~T[/tex] or [tex]7,24 \times 10^{-3}~T[/tex] with the resultant inward.
Penjelasan dengan langkah-langkah:Diketahui:
Kawat melingkar L₁ dengan radius r₁ = 7 cm dialiri arus listrik 12 A.Kawat melingkar L₂ dengan N = 30 lilitan dan radius r₂ = 1,6 cm dialiri arus listrik 3 A.Kedua kawat sepusat pada titik P.Ditanya:
Berapakah resultan medan magnet di titik P jika kedua arus mengalir dalam arah yang berlawanan?
Proses:
Rumus induksi medan magnet kawat melingkar di pusat lingkaran adalah sebagai berikut.
[tex]\boxed{B=\frac{\mu_0 I N}{2a} }[/tex]
Keterangan:
B = medan magnet (T atau Wb/m²)I = kuat arus (A)N = banyak lilitana = radius (m)[tex]\mu_0 = 4\pi \times 10^{-7}[/tex]Aturan tangan kanan pada kawat melingkar berarus.
Arah B = arah ibu jariArah I = arah putaran keempat jari tanganStep-1: hitung medan magnet L₁
[tex]\boxed{B_1=\frac{(4\pi \times 10^{-7})(12)(1)}{2(7\times 10^{-2})} }[/tex]
[tex]B_1=3,43\pi \times 10^{-3}~T[/tex] dengan vektor B₁ berarah ke dalam.
Step-2: hitung medan magnet L₂
[tex]\boxed{B_2=\frac{(4\pi \times 10^{-7})(3)(30)}{2(1,6\times 10^{-2})} }[/tex]
[tex]B_2=1,125\pi \times 10^{-3}~T[/tex] dengan vektor B₂ berarah ke luar
Step-3: hitung resultan medan magnet di titik P
Misalnya acuan arah positif adalah ke dalam, maka [tex]\Sigma B = B_1 - B_2.[/tex]
[tex]\Sigma B = 3,43\pi \times 10^{-3}- 1,125\pi \times 10^{-3}[/tex]
[tex]\therefore \Sigma B = 2,305\pi \times 10^{-3}~T[/tex] atau [tex]\Sigma B = 7,24 \times 10^{-3}~T.[/tex]
Karena hasilnya positif, maka resultan medan magnetik berarah ke dalam.
