An earth satellite is moved from one stable circular orbit to another larger and stable circular orbit. The following quantities increase for the satellite as a result of this change

A

gravitational potential energy

B

angular vleocity

C

linear orbital velocity

D

centripetal acceleration

Solution

$U=-\frac{u M m}{r}, \omega=\sqrt{\frac{G M}{r_{3}}}, \sqrt{\frac{G M}{r}}, a_{1}=r \omega^{2}$

So only option $(A)$ is correct.
