Two equal forces (P each) act at a point inclined to each other at an angle of `120^@`. The magnitude of their resultant is

A

`(P)/(2)`

B

`(P)/(4)`

C

P

D

2P

Text Solution

Verified by Experts

The correct Answer is:
C
`R=sqrt(A^(2)B^(2)+2ABcostheta)`
If `A=B=P` and `theta=120^(@)` then `R=P`
