    Gas escapes from the surface of a planet because it acquires an escape velocity. The escape velocity will depend on which of the following factors : Mass of the planet Mass of the particle escaping Temperature of the planet Radius of the planet Select the correct answer from the codes given below: [SCRA 1994]

    A)      I and II

    B)                           II and IV

    C)             I and IV

    D)               I, III and IV

    Correct Answer: C

    Solution :

                    \[{{v}_{e}}=\sqrt{\frac{2GM}{R}}\]i.e. escape velocity depends upon the mass and radius of the planet.
