Question

What will be the force of attraction between two bodies weight 20 kg and 50 kg with a distance of 2 metre between them?

Answer 1

Given:-
m1 = 20kg
m2 = 50kg
r = 2 m
G = 6.67 × 10^ -11
To find :-
F= ?

By newtons law of gravitation
F = Gm1m2÷ r^2
$6.67 \times {10}^{ - 11} \times 20 \times 50 \div {2}^{2}$
= 1667.5 × 10−11 N
