The correct option is A gravitational potential energy
Lets see the formulae for each quantity given there,
Gravitational potential energy =−GMmr
angular velocity =(GMr3)0.5
linear orbital velocity =(GMr)0.5
centripetal acceleration =GMr2
We can observe that, the quantities in the options B,C,D are all indirectly proportional to r
i.e. ω, v, a α1rn where n is distinct postive interger in each quantity.
So, with increase in r all these quantities decrease.
Now, (-potential energy) α1r i.e. negative of potential energy decreases with increase in r. Therefore, potential increases with increase in orbital radius.
