Question

If an unbalanced force acts on a body, the body must accelerate.

• A. True
• B. False

Answer 1

The correct option is A True

1. According to Newton's second law, $F=ma$, when there is an unbalanced force, the body will have non zero acceleration because mass is a constant.
2. So the statement “If an unbalanced force acts on a body, the body must accelerate” is true.
