Question

An artificial satellite moves in a circular orbit around the earth. Total energy of the satellite is given by $E$. Then the potential energy of the satellite is

• A. $-2E$
• B. $2E$
• C. $\frac{2E}{3}$
• D. $\frac{-2E}{3}$

Answer 1

The correct option is B $2E$

$P.E=2(T.E)$

$P.E\to$ Potential Energy

$T.E\to$ Totala Energy

$\therefore P.E=2E$
