Question

19. Soni says that the acceleration of an object could be zero even when several forces

are acting on it. Do you agree with her? Why?

​

Answer 1

Yes, I agree with Soni . This is because acceleration in an object could be zero even when several forces are acting on it if the resultant force( F) is zero. We know that F= m× a. Now , when force, F= 0, then acceleration(a) has to be zero because mass (m) cannot be zero.

Answer 2

Ans. Yes, we agree with her statement. Because when many balanced forces acting on the

object its displacement becomes zero.
