A satellite is orbiting round the earth in a circular orbit with speed v. If m is mass of satellite its total energy is:

Options

A. `(1)/(2)mv^(2)`
B. `mv^(2)`
C. `-(1)/(2)mv^(2)`
D. `(3)/(4)mv^(2)`.

Answer

C

Explanation

Total energy = -(kinetic energy `=-(1)/(2)mv^(2)`
Thus correct choice is (c ).
