Verified Solution • 2025–26 Session moderate

Match List I with List II :

	LIST I		LIST II
A.	Kinetic energy of planet	I.	$- GMm / a$
B.	Gravitation Potential energy of sun-planet system	II.	$GMm / 2 a$
C.	Total mechanical energy of planet	III.	$\frac{Gm}{r}$
D.	Escape energy at the surface of planet for unit mass object	IV.	$- GMm / 2 a$

(Where $\mathrm{a}=$ radius of planet orbit, $\mathrm{r}=$ radius of planet, $\mathrm{M}=$ mass of Sun, $\mathrm{m}=$ mass of planet)

Choose the correct answer from the options given below :

Accepted Answer

$\text { K.E }=\frac{G M m}{2 a} \quad \text{(II)}$

$U_G=\frac{-G M m}{a} \quad \text{(I)}$

$M . E=\frac{-G M m}{2 a} \quad \text{(IV)}$

$\text { and Escape Energy }=\frac{G m}{r} \quad \text{(III)}$
