Question

derive how does the value of gravitational fonce f change between two objects when mass of one object is increased four times

Answer 1

gravitational force f is directly proportional to product of masses of two objects

we have formula

f=g*m1*m2/r^2

hence when mass of one object is increased by 4 times

f=g*4*m1*m2/r^2

force will also increase by 4 times since it is directly proportional to product of masses

hence gravitational force will increase by 4 times when mass is increased by 4 times
