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.
