NEET Physics Newton's Laws Assertion Reason Question
Assertion (A): A body at rest will remain at rest unless acted upon by a net external force.
Reason (R): A free-body diagram of a resting body shows no forces acting on it.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
According to Newton's first law, a body at rest remains at rest unless acted upon by an external force. A free-body diagram includes all forces acting on the body, even if they balance out, so R is incorrect.
