Question

Why does the Earth exert a gravitational force on objects on its surface?

Answer 1

Answer:

B. It has mass

Explanation:

The Newtons Universal gravitacion law is : F = G.$\frac{m1 m2}{d^{2} }$  , where F is the force exerted , m1 and m2 are the earth's mass and the object's mass, d is the distance and G the gravitacional constant. Comparing to the options we can say that the Earth exerts a gravitational force on objects on its surface because of its mass.
