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:

Soni is right because when the object is at rest and its speed is zero, the acceleration becomes zero. An object can have many forces acting simultaneously, but they can cancel or neutralize each other, when the object is in motion with the same velocity, in that case the acceleration is zero. Even in such a situation many balancing forces can act on an object simultaneously.
