Correct answer: B
(a) $$[G] = {{F{r^2}} \over {{m_1}{m_2}}}$$
$$[G] = {{F{r^2}} \over {{m_1}{m_2}}} = {{[ML{T^{ - 2}}]{L^2}} \over {[MM]}} = [{M^{ - 1}}{L^3}{T^{ - 2}}]$$
(b) Gravitational potential energy $ = [M{L^2}{T^{ - 2}}]$
(c) Gravitational potential $$ = {{PE} \over m} = [{L^2}{T^{ - 2}}]$$
(d) Gravitational field intensity $$ = {F \over m} = [L{T^{ - 2}}]$$
