Answer:
Given,
Mass of Earth = 6*10^24 kg
Mass of Moon = 7.4*10^22 kg
Distance between them = 3.8*10^5 km
= 3.8*10^8 m
Gravitational Constant = 6.67*10^-11 N.m^2.kg^-2
= F = (G*m1m2)/r^2
= (6.67*6*7.4*10^24+22+(-11)) / (3.8*10^8)^2
= (296.148*10^35) / (14.44*10^16)
= (296.148/14.44) * (10^35-16)
= 20.50*10^19 N
or,
= 2.05*10^20 N
Hope this helps.
