Q. 19.     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?

Answers (1)

Yes. If all the external forces acting on the body balances each other then the net force acting on the object is zero. Thus the acceleration produced is zero even if forces are acting on the body. The necessary condition for the zero acceleration is that the net force acting on the body should be zero.
