$\huge\star\green{{answer...!! }}$

• The change in gravitational potential energy, ΔPEg, is ΔPEg = mgh, with h being the increase in height and g the acceleration due to gravity. The gravitational potential energy of an object near Earth's surface is due to its position in the mass-Earth system.

V = k × [q/r]

V = electric potential energy,

q = point charge,

r = distance between any point around the charge to the point charge,

k = Coulomb constant; k = 9.0 × 109 N.
