Question

Assuming the Earth to be a sphere of uniform mass density, how much would a body weight half way down to the centre of the Earth, if it weighed 300N on the surface of Earth.

Answer 1

Answer:

Hey mate here is your answer.//

Explanation:

We know,

accⁿ due to gravity at depth h from earth's surface ,

g = go( 1 - h/r),

here, h = r/2,

g = go(1 - r/2r) = go/2,

Now, weight of body at the surface of the earth = 300N = mgo,

hence, weight of body at depth R/2 = mgo/2 = 300/2 = 150 N.
