Question

Two balls with masses 2kg and 4kg respectively at a distance r

Answer 1

Then gravitational force between these two bodies is given by:-

F = G(m1m2)/r²

F = G (8)/r²

Answer 2

Answer:

mass of body is Ma=2kg

mass of body b is Mb=4kg

mass of body c is Mc=1kg

seperation between a and b=2m

let the bodies see we placed at a distance D from the body A,

the gravitational force between a and c,

FAC=GMaMc/d^2=G*2*1/d^2=2G/d^2.......the gravitational force between b and c is.
