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

Step-by-step solution

The magnitude of the resultant force can be given by parallelogram's law of vector addition i.e., aligned F_ net &= 2 p²+2 p² (120^ ) ( =120^ ) &= 2 p²+2 p² (- 1 2 ) &= p² &=p aligned
