Question

a body of mass of 10kg on the surface of the earth. what will be its wieght when taken to the central of the earth

Answer 1

At the centre of the earth gravity is zero.
So, weight = mass x gravity  
                 = 10 x 0
                  = 0

So, the body will weigh zero.

Hope it helps ^_^

Answer 2

its weight at the center of the earth will be 0. because acceleration due to gravity is 0 there. and weight= m*g
                               W=10*0
                               W=0 N
                                
        i hope that this will help u............^_^
