Question

Match the combinations in Column I with their possible SI units in Column II.

Match the following List-I with List-II:

List - I	List - II
(I) $\frac{G m ^{2}}{r}$ ( $G$ - gravitational constant, $m$ - mass, $r$ - distance )	(P) joule
(II) $\frac{1}{2} k x^{2}$ ( $k$ - spring constant, $x$ - extension )	(Q) $(kg) (metre)^{2} (second)^{- 2}$
	(R) newton
	(S) watt

r G m 2 ​ = r F r 2 ​ = F r → energy [ M L 2 T − 2 ] ; 2 1 ​ k x 2 is spring potential energy [ M L 2 T − 2 ] . Both match joule ( p ) and ( kg ) ( m ) 2 ( s ) − 2 ( q ) .
