SATHEE: Kinematics Question 7

Kinematics Question 7

Question: Two forces, each of magnitude F have a resultant of the same magnitude F. The angle between the two forces is [CBSE PMT 1990]

Options:

A) $45^{\circ}$

B) $120^{\circ}$

C) $150^{\circ}$

D) $60^{\circ}$

Show Answer

Answer:

Correct Answer: B

Solution:

$R = \sqrt{A^{2} + B^{2} + 2 A B \cos θ}$

By substituting, $A = F, B = F$ and $R = F$ we get

$\cos θ = \frac{1}{2} ∴ θ = 120^{\circ}$
