Question

Calculate force of gravitation between two object of mass 50 kg and 120 kg respectively kept at a distance of 10 m from one another gravitational constant g is equal to 6.7 into 10 power minus 11 newton metre square per kg square

Answer 1

F = GMm/r square
6.67×10minus 11 × 50 × 120/100
= 4.02 × 10 power minus 11 N
