Question

An artificial satellite moves in a circular orbit around the earth. Total energy of the satellite is E. then what is the potential energy of satellite (A) -2E (B) 2E (C) (2E/3) (D) (-2E/3)

Tardigrade Admin · Accepted Answer

U =(- GM e m / R e ) KE =(1/2) ( GM e / R e ) TE = U + K =(-1/2) ( GM e m / R e ) U =-2 E

Q. An artificial satellite moves in a circular orbit around the earth. Total energy of the satellite is $E$ . then what is the potential energy of satellite

$- 2 E$

$2 E$

$\frac{2 E}{3}$

$\frac{- 2 E}{3}$

$U = \frac{- G M _{e} m}{R _{e}}$
$K E = \frac{1}{2} \frac{G M _{e}}{R _{e}}$
$TE = U + K = \frac{- 1}{2} \frac{G M _{e} m}{R _{e}}$
$U = - 2 E$
