Three forces start acting simultaneously on a particle moving with velocity v. These forces are represented in magnitude and direction by the three sides of a triangle ,ABC (as shown). The particle will now move will velocity

a
v, remaining unchanged
b
less than v
c
greater than v
d
v in the direction of the largest force BC

detailed solution

Correct option is A

Here, the three forces are along the three sides of a triangle taken in same order. Therefore, their resultant is zero. Now according to Newton's law, the body will continue to move with the same velocity.
