it is because the acceleration of gravity measure with radius and at center radius is zero so automatically value of g is zero

tanujaprabhudesai: can you explain this in brief pls edit ans. and explain

hey buddy,

looks like u r in 9

g = GM/r²

so as ur question....

when we move to the centre of earth, the radius of the earth decreases.

so u may be wondering that why value of g decreases instead of increasing.. bcoz g is inversely proportional to r( radius of earth)

but on doing so.. the mass of the earth also decreases ( actually mass of the earth do not decreases but the mass of the part of the earth which is beyond us is not counted)

so in the centre of the earth that mass would be zero... and therefore g will be zero in the earth's centre..

hope that helps✌️✌️
