Expert Answer
(1)
g = GM/R2
M' = 0.99M
R' = 0.99R
g' = GM'/R'2 = 0.99GM/(0.99R)2 = g/0.99 = 1.01g
Hence g will increase by 1%.
(2) g' = GM'/R'2 = 1.01GM/(1.01R)2 = g/1.01 = 0.99g
Hence g will decrease by 1%.
(3) g' = GM'/R'2 = 1.01GM/(0.99R)2 = 1.03g
Hence g will increase by 3%.
Similarly it can be worked out for other cases.
