4-1.Newton's Laws of Motion
easy
A body under the action of several forces will have zero acceleration
AWhen the body is very light
BWhen the body is very heavy
CWhen the body is a point body
DWhen the vector sum of all the forces acting on it is zero
Solution
(d) $\vec a = \frac{{\vec F}}{m}$.
If $\vec F = 0$ then $\vec a = 0$.
If $\vec F = 0$ then $\vec a = 0$.
