NEET Physics Equilibrium of Forces Assertion Reason Question
Assertion (A): A box on the floor of an accelerating train experiences a net force even if it remains stationary relative to the train.
Reason (R): The force of friction is the only conceivable force causing the acceleration of the box.
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 the NCERT context, the force of friction is what causes the box to accelerate along with the train, even if it remains stationary relative to the train. Thus, R correctly explains A.
