Question

state the following statement is true or false
1. the value of 9 decreases as we go deep inside the earth

2. the value of 9 at the centre of the earth is zero

please answer this questions​

Answer 1

heyyy❤

The gravitational flux, through any closed surface, is proportional to the enclosed mass." In integral form, So gravity decreases with increase in depth as the effective mass applying the gravitational force decreases as you go down. If you are 1/4 below the surface of a completely homogeneous planet of equal density.

At the centre the distance is zero, hence gravity is zero. The value of 'g' is 9.8. 'g' is acceleration due to gravity.At the centre of the earth it will turn zero because there will be no acceleration at the centre of the earth
