Question

Match the column I with column II.

(where is the mass of the earth, m is mass of the satellite and r is the radius of the orbit)

	Column I		Column II
(A)	Kinetic energy	(p)
(B)	Potential energy	(q)
(C)	Total energy	(r)
(D)	Orbital velocity	(s)

• A. A –r, B – s, C – q, D –P
• B. A – q, B – p, C- r, D – s
• C. A – p, B – q, C – s, D – r
• D. A – S, B – r, C – p, D – q

Answer 1

Answer: (D)

A – S, B – r, C – p, D – q

Answer 2

Kinetic energy =

A –s

Potential energy

B – r

Total energy

C – P

Orbital velocity$= \sqrt { \frac { \mathrm { GM } _ { \mathrm { E } } } { \mathrm { r } } }$

D – q
