Benson · Answer 1

Force = 49 N

Explanation:

The gravitational force of attraction on the surface of earth F = G M m/R²

Here G = gravitational constant = 6.67 x 10⁻¹¹

M = mass of the earth and m = mass of the body on the surface of earth.

R = radius of earth

In this question

mass of earth = 6 x 10²⁴ kg and its radius = 6 x 10⁶ m

The values are substituted in the above equation

F = 6.67 x 10⁻¹¹ x 6 x 10²⁴ x 5 / (6 x 10⁶) ² = 49 N

The mass will be attracted by 49 N of force.
