Answer:a) 3.56 x 10^22 Nb) 3.56 x 10^22 NExplanation:Mass of the sun M = 2 x 10^30 kg

mass of the Earth m = 6 x 10^24 kg

Distance between the sun and the Earth R = 1.5 x 10^11 m

From Newton’s law,

F =

where F is the gravitational force between the sun and the Earth

G is the gravitational constant = 6.67 × 10^-11 m^3 kg^-1 s^-2

m is the mass of the Earth

M is the mass of the sun

R is the distance between the sun and the Earth.

Substituting values, we have

F = =

3.56 x 10^22 NA) The force exerted by the sun on the Earth is equal to the force exerted by the Earth on the Sun also, and the force is equal to

3.56 x 10^22 Nb) The force exerted by the Earth on the Sun =

3.56 x 10^22 N
