An object of mass 0.50 kg is transported to the surface of planet x where the object's weight is measured to be 20 n. the radius of the planet is 4.0 ´ 106 m. what free fall accerleration will the 0.5 kg object experience when at the surface of planet x. what is the mass of planet x? (g = 6.67 ´ 10-11 n × m2/kg2)

Mass of the planet,

Explanation:

Given that,

Mass of the object, m = 0.5 kg

Weight of the object, W = 20 N

Radius of the planet,

The weight of an object is given by :

W = mg

g is the acceleration due to gravity on the surface of Planet

The expression for g is given by :

So, the mass of the planet X is . Hence, this is the required solution.                                

it may be wrong but i think its a
