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 ?

Text Solution

Verified by Experts

Yes, I agree with her. This is because the 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 xx a`. Now, when force F = 0, then acceleration 'a' has to be 0 (because mass 'm' cannot be 0).
