Question

plz solve this question

Answer 1

since we know that g is equal to GM/R^2

and M`=2M,R`=1/2R

then,g=GM`/(1/2R)^2

=g=G2M/(1/4)R^2

=g=2×4×GM/R^2

=g=8×g. (as GM upon Rsquare is g)

Answer 2

since we know that g is equal to GM/R^2

and M`=2M,R`=1/2R

then,g=GM`/(1/2R)^2

=g=G2M/(1/4)R^2

=g=2×4×GM/R^2

=g=8×g. (as GM upon Rsquare is g
