MCQ
A body under the action of several forces will have zero acceleration
  • A
    When the body is very light
  • B
    When the body is very heavy
  • C
    When the body is a point body
  • When the vector sum of all the forces acting on it is zero

Answer

Correct option: D.
When the vector sum of all the forces acting on it is zero
d
(d) $\vec a = \frac{{\vec F}}{m}$.

If $\vec F = 0$ then $\vec a = 0$.
