F = - G

Mm

r2

(G is the Universal constant of gravity.)

According to Newton’s universal law of gravity, the sun is attracting the Earth with a force of 3.6*122 N. What is the gravitational force that the Earth exerts on the sun?

According to Newton’s universal law of gravity, the sun is attracting the Earth with a force of 3.6*122 N. What is the gravitational force that the Earth exerts on the sun?

1.75*118 N

3.6*122 N

1.95*129 N.

Depends on the relative speed of the Earth with respect to the sun.
