Gas escaps from the surface of a planet because it acquires an escape velocity. The escape velocity will depend on which of the following factors :
I. Mass of the planet
II. Mass pf the particle escaping
III. Temperature of the planet
IV. Radius of the planet
Select the correct answer from the codes given below.

Options

A. I and II
B. II and IV
C. I and IV
D. I, II and IV

Answer

C

Explanation

`v_(e)=sqrt((2GM)/(R))` i.e., escape velocity depends upon the mass and radius of the planet.
