Question

Soni says that the acceleration in an object could be zero even when several forces are acting on it. Do you agree with her? Why?

Answer 1

If the resultant force acting on a body in different directions is zero, then the acceleration will be zero. 

We know that,                               F = ma, 

In the net force is zero,                 F = 0, then ma = 0 

                                                      ⇒ a = 0               [as m ≠ 0]
