calculate the force of gravity between the earth ( mass 6*10 ^ 24) and the sun ( mass 2*10^30 ) the average distance between the two is 1.5 * 10^11 meter compare this with force of gravitation between two hundred kg masses separated by a distance of 1 kilometres

Answer:
Mass of earth = M = 6 × 10²⁴ Kg
mass of sun = m = 2×1030 Kg
distance between earth and sun = r = 1.5 × 10¹¹ m
According to the universal law of gravitation, F=GMmr2
( where , G=6.67×10−11 )
F=(6.67×10−11×6×1024×2×1030)(1.5×1011)2
F=6.67×6×22.25×1013×1030×10−22
F = 35.57 × 10²¹ N
F = 3.557 × 10²² N.
