Question

If the acceleration due to gravity on the surface of earth is g, then the acceleration due to gravity on the surface of a planet whose mass is half of that of earth and radius is same as that of earth is

Answer 1

Answer:

g = Gm\ 2r(square)

Explanation:

gravity of planet = g

mass of earth = m

mass of planet = m\2

mass of object on surface of planet M

radius = r

force = f

acceleration due to gravity on planet = g

f = GMm\2 r(square)

Mg = GMm\2 r(square)

g = Gm \2 r(square)
