SATHEE: Kinematics Question 39

Kinematics Question 39

Question: Two equal forces (P each) act at a point inclined to each other at an angle of 120°. The magnitude of their resultant is [Karnataka CET 2004]

Options:

A) $P / 2$

B) $P / 4$

C) $P$

D) 2P

Show Answer

Answer:

Correct Answer: C

Solution:

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

If $A = B = P$ and $θ = 120^{\circ}$

then $R = P$
