Question

waht is a force of gravation betwen object of masses 10 kg and 20 kg when distance between their centre 10m

Answer 1

$f = \: 1.334 \times {10}^{ - 12} newton$

Answer 2

M=20 gm
m= 10 gm. , r= 10m
F = G M m / r2 = 6.67 ×(10)-11 in power of 10 ×20×10/(10)square = 13.34 × (10 )-11 Newton.
