The mass of venus is 81.5% of the earth and its radius is 94.9% that of the earth. a)compute the acceleration due to gravity on the surface of venus from these data. b)if a rock weighs 75.0n on earth, what would it weigh on the surface of venus?

Part a)

Part b)

Explanation:

As we know that the acceleration due to gravity is given as

where we know that

M = mass of planet

R = radius of planet

if we plug in mass of earth and radius of earth in above equation then we will have

now if we will find it for Venus

now from above formula again

Part b)

If Rock weigh 75 N on surface of Earth

then we have

now on the surface of Venus its weight is given as

good looking response
