Answer:
100N
Explanation:
Acceleration due to gravity at a depth d from surface of earth
g° = g(1 - d/r) .....(1)
Where g = acceleration due to gravity at earth's surface
Multiplying by mass 'm' on both sides of (1)
mg° = mg(1- d/r) ------------ (d=r/2)
= 200(1- r/2r) = 200(1-1/2) = 200 × 1/2 = 100N
