Q. Three forces starts acting simultaneously on a particle moving with velocity $\overrightarrow{v}$. These forces are represented in magnitude and direction by the three sides of a triangle $ABC$ (as shown). The particle will now move with velocity
A) $\overrightarrow{v}$ remaining unchanged
B) Less than $\overrightarrow{v}$
C) Greater than $\overrightarrow{v}$
D) $\overrightarrow{v}$ in the direction of the largest force $BC$
Explanation
(a) Net force on the particle is zero so the $\overrightarrow{v}$ remains unchanged
