What is the gravitational force acting on a 54.0kg object on earth’s surface?

529.2N

Explanation:

Given parameters:

Mass of the object  = 54kg

Unknown:

Gravitational force acting on the mass  = ?

Solution:

To solve this problem, the gravitational force acting on this body is tantamount to the weight of the object.

         So;

    Weight  = mg

m is the mass

g is the acceleration due to gravity

    Now;

     Weight  = 54 x 9.8  = 529.2N

The gravitational force acting on the object is 529.2N

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
