हिन्दीA satellite of mass \( m \) is orbiting in a circular orbit of radius \( r \) around a planet of mass \( M \). What is the ratio of its kinetic energy \( K \), potential energy \( U \), and total mechanical energy \( E \)?
Correct answer · Option 4
\( 1 : -2 : -1 \)
Explanation
\( K = \frac{GMm}{2r} \), \( U = -\frac{GMm}{r} \), \( E = -\frac{GMm}{2r} \). Hence \( K : U : E = 1 : -2 : -1 \).
