Question

A body weighs 36 kg on the surface of the earth. How much would it weigh on the surface of a planet, whose mass is 1/ 4 and radius is 1/2 of that of the earth ?

Answer 1

Answer: 36N

Explanation:

g = (GM/(R^2))

Then , when M' = M/4 & R'= R/2 then , the value of g' = g

Then the weight in earth = weight on that planet
