If radius of an orbiting satellite is decreased, then its kinetic energy

Question

If radius of an orbiting satellite is decreased, then its kinetic energy (A) And potential energy decrease (B) And potential energy increase (C) Decreases and potential energy increases (D) Increases and potential energy decreases

Tardigrade Admin · Accepted Answer

K.E =(G M m/2 r) P.E =-(G M m/r) M arrow mass of planet m arrow mass of satellite r arrow radius of orbit When r is decreased, Kinetic energy increases, Potential energy decreases (becomes more negative).

Q. If radius of an orbiting satellite is decreased, then its kinetic energy

And potential energy decrease

And potential energy increase

Decreases and potential energy increases

Increases and potential energy decreases

$K . E = \frac{GM m}{2 r}$
$P . E = - \frac{GM m}{r}$
$M \to$ mass of planet
$m \to$ mass of satellite
$r \to$ radius of orbit
When $r$ is decreased,
Kinetic energy increases,
Potential energy decreases (becomes more negative).
