Solution

The correct option is A by 0.5% decrease
Apparent acceleration due to gravity at height h, g=g(12hR)
ggg=2hR
Percentage decrease in weight, mgmgmg×100=2hR×100
2hR×100=1 %

OR hR×100=0.5 % .............(1)

Apparent acceleration due to gravity at depth h, g1=g(1hR)
gg1g=hR
Percentage decrease in weight, mgmg1mg×100=hR×100=0.5 % (using (1))
