NEET Physics Variation of g with Depth MCQ Question with Solution

A body weighs 250 N on the surface of the Earth. How much will it weigh halfway down to the centre of the Earth?

A

125 N

B

150 N

C

175 N

D

250 N

Option A

Weight at a depth d is given by W = W₀(¹⁻ d/R). At halfway, d = R/2, so W = 125 N.
