Solve the followi
Answer :
Mass of planet M = 8 x mass of earth = 8 x 6 x 1024 kg
Radius of planet R = 2 x radius of earth = 2 x 6.4 x 106 m
G = gravitational constant = 6.67 x 10-11 N m2/kg2
So escape velocity = √
Escape velocity =
= 22.4 km/sec.
So escape velocity of the planet will be 22.4 km/sec
