Question

calculate the force of gravitation between two objects of masses 50 kg and 120 kg respectively kept at a distance of 10 metre from one another

Answer 1

$g = \frac{6.67 \times {10}^{ - 11} \times m1 \times m2}{ {r}^{2} } \\ = \frac{6.67 \times {10}^{ - 11} \times 50 \times 120 }{ {10}^{2} } \\ = \frac{6.67 \times {10}^{ - 11} \times 6000 }{100} \\ = 6.67 \times {10}^{ - 11} \times 60 \\ = 400.2 \times {10}^{ - 11} \\ = 4.002 \times {10}^{ - 13} newton$
