Question

the earth attracts every object toward itself with a force. calculate the gravitational force exerted by earth oneach of your family members. what is the gravitational force exerted by each of the family member on earth?​

Answer 1

Given:

The earth attracts every object toward itself with a force.

To find:

• The gravitational force exerted by earth on each of your family members.

• The gravitational force exerted by each of the family member on Earth.

Calculation:

Let mass of one family member be m and mass of earth be M ;

Now , gravitational force is a mutual force which is dependent on the product of the masses.

Let's considerthat the family member is standing on the earth surface. So , we can consider the distance between the family member and the earth to be approximately equal to the radius of the earth.

$\boxed{ \sf{F = \dfrac{GMm}{ {r}^{2} } }}$

So , the family member exerts equal and opposite force on the earth as compared to the force exerted by earth on family member.
