Question

Match the following

Table–1	Table–2
(A) kinetic energy	(P) [(– GMm) / (2r)]
(B) Potential energy	(Q) √(GM / r)
(C) Total energy	(R) – [(GMm) / r]
(D) orbital velocity	(S) [(GMm) / (2r)]

Answer 1

A-S,    

B-R,     

C-P,     

D-Q   

Explanation:

(A) kinetic energy = [(GMm) / (2r)]

(B) Potential energy = – [(GMm) / r]

(C) Total energy = [(– GMm) / (2r)]

(D) orbital velocity = √(GM / r)

i.e. A → S 

B → R 

C → P 

D → Q
