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

Answer
(d) As, escape velocity $=\sqrt{\frac{2 G M}{R}}$, so its value depends on mass of planet and radius of the planet. The two different planets have same escape velocity, when these quantities (mass and radius) are equal.
