g the total mechanical energy of the satellite-Earth system when the satellite is in its current orbit is E. In order for the satellite to orbit Earth in a new stable circular orbit at an altitude of 12RE, the energy of the satellite-Earth system must be

The correct answer is "".

Explanation:

According to the question,

Energy of satellite,

⇒

For the very 1st case:

or,

⇒ ...(1)

For the new case:

then,

⇒

        ...(2)

From equation (1) and (2), we get

⇒

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

an energy transformation flow diagram is shown
