# Solve the followi

Answer :

Mass of planet M = 8 x mass of earth = 8 x 6 x 10^{24} kg

Radius of planet R = 2 x radius of earth = 2 x 6.4 x 10^{6} m

G = gravitational constant = 6.67 x 10^{-11} N m^{2}/kg^{2}

So escape velocity = √

Escape velocity =

= 22.4 km/sec.

So escape velocity of the planet will be 22.4 km/sec
