Question

Based on Newton's Law of Gravitation
1. Two pieces of iron are kept at a distance of 20 cm. The
mass of each of the pieces is 100 kg. What is the gravi-
tational force acting between them? Given,
G = 6.67 x 10-11 N·m2. kg-2. [1.67 x 10-5N)​

Answer 1

Explanation:

f=GMm/r^2

f=6.67*10^-11*100*100/0.04

f=6.67*10^-7*25

f=1.67*10^-5
