the value of gravity is 0 at the centre of earth

hope it helps


vikas1247: It is not exactly 0 but it is too weak at centre so it is considered as 0
vansh3140: radius of earth at centre=0
anamika91: ys
vansh3140: f=GmM/R^2 as R =0 therefore 1/0 =infinity (nothing)
anamika91: ok
Fiza001: Hii

When we move towards centre of earth, the mass is equally distributed in all directions.

The mass beneath you = Mass in front of you = Mass behind you

Thus, all the gravitational forces applied cancel each other and acceleration due to gravity (g) at centre of earth on centre of earth becomes zero (0).
