Chapter 6, Problem 1Q

To determine

To Choose:The correct option.

Explanation of Solution

Given:

The Earth exerts a gravitational force of $2.0\times {10}^{20}\text{N}$ on the Moon.

Formula Used:

According to Newton’s third law of motion, for every action, there is equal and opposite reaction.

  $F_{AB}=-F_{BA}$

Calculation:

By Newton’s third law of motion, if the Earth exerts a gravitational force of $2.0\times {10}^{20}\text{N}$ on the Moon, the moon also exerts same force on the Earth.

Conclusion:

Thus, option (c) is correct.
