Question 395: Gravitation

Question

Match List - I with List - II

List - I

List - II

(a)
Gravitational constant (G)
(i)
$$[{L^2}{T^{ - 2}}]$$

(b)
Gravitational potential energy
(ii)
$$[{M^{ - 1}}{L^3}{T^{ - 2}}]$$

(c)
Gravitational potential
(iii)
$$[L{T^{ - 2}}]$$

(d)
Gravitational intensity
(iv)
$$[M{L^2}{T^{ - 2}}]$$

Choose the correct answer from the options given below

Accepted Answer

(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 $$ = {F \over m} = [L{T^{ - 2}}]$$
