Question

If the distance between two objects is increased four times, then by how many times will the mass of one of the object will be changed to maintain the same gravitational force

Answer 1

as ji is directly proportional to mass and inversely proportional to the square of distance

as distance is increased by 4 times so g is reduced by 16 times

in order to maintain the same gravitational force the mass of an object should be increased by 16 times
