Question

The escape velocity of a body from earth's surface is
11.2 Km/sec. if the radius of another planet be half the
radius of the earth and its mass be one fourth of the
mass of the earth. Calculate the escape velocity from
this planet.​

Answer 1

Answer:

15.84 ms^-1

Explanation:

Here, R(unknown) = Re/2

M(unknown) = Me/4

so, Ve/V(unknown) = (2GMe/Re)^0.5/(2G*(Munknown)/R(unknown))^0.5

V(unknown) = 15.84 m/s
