Solve the following problems. If mass of a planet is eight times the mass of the earth and its radius is twice the radius of the earth, what will be the escape velocity for that planet?

Question

Philoid · Accepted 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
