1) Zero in answer

Explanation:

i hope you understand

Answer 2

Answer:

The gravity potential at centre would be zero

Explanation:

• The gravity potential needs to be found out in this situation where mass of Earth is given as m and Radius is given as r and the gravitational potential at the surface is given as -Vo.

Applying the formula for Gravity potential,

                       $M \times G \times H= m \times g \times R$ = -Vo

• This is the gravity potential on surface of finding gravity potential at centre radius will be equal to zero.

So applying this value in formula,

                                 $M \times G \times H=0.$

• Since radius is equal to zero hence we get this gravity potential as 0.
