Assertion: Two different planets have same escape velocity.
Reason: Value of escape velocity is a universal constant.

Options

A. If both the assertion and reason are true and reason is a true explantion of the assertion.
B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.
C. If the assertion is true but reason false
D. If both the assertion and reason are false.

Answer

D

Explanation

As escape velocity `=sqrt((2GM)/R)`, so its value depends on mass of planet and radius of the planet. The two different planets have same escape velocities, when these quantities (mass and radius) are equal.
