Question:

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?

Answer:

Ans: 22.4 km/s.

Answer 2

Answer:

22.4km/s

Explanation:

escape velocity= under root( 2Gm/r)

G=universal gravitation constant

m=mass of planet

r=radius of planet

according to given conditions we get

(Vesp)planet=2×(Vesp)earth

=2×11.2 =22.4 km/s
