Physics-Escape Velocity

NEET Physics Escape Velocity Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 11

Assertion (A): The escape velocity from the surface of the Earth depends on the gravitational constant, the mass of the Earth, and the radius of the Earth. | Reason (R): The escape velocity is derived using the principle of energy conservation, equating kinetic energy with gravitational potential energy.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

The assertion and reason both are correct as the escape velocity formula ViE=2gREV_{iE} = \sqrt{2gR_E} incorporates the gravitational constant, mass of the Earth, and radius of the Earth, derived from equating kinetic and potential energy.
