Assuming the earth to be a sphere of uniform mass density, the weight of a body at a depth d = 
from the surface of earth, if its weight on the surface of earth is 200 N, will be: (Given R = radius of earth)
Text Solution
Verified by ExpertsThe correct answer is:
B
The acceleration due to gravity with depth is
The given data is
W = 200 N
Let the weight be at the given depth, W’ Hence, the value is
The Weight 
= 100 N
