Question

If g and G stand for acceleration due to gravity and
gravitational constant respectively, then at the centre of the Earth
(a) g = 0
(b) G = 0
(c) g = G = 0
(d) None of these​

Answer 1

Answer:

a) g= 0

As g can vary but G remains constant

Answer 2

Answer:

g is very from place to place

option no. (a) g = 0

because at center the upper force will cancelled with lower force therefore the the net forces will be 0

so, the g will be also zero

and G is universal gravitational constant

so it cannot very
