PE = m•g•h, where m is mass in kg, g is 9.8m/s2, and h is height in meters.
PE = 5.0kg x 9.8m/s2 x 2.0m = 98kg•m2/s2 = 98 Joules
Potential Energy is defined by the equation Ep = mgh
so:
Ep = mgh
Ep = (0.5)(9.81)(2)
Ep = 9.81 Joules

There is potential energy, which is non-zero if you are above ground level (or above, or below, any other reference level you choose).
Imagine a plate sitting on a table. Becasue it isn't moving, the plate has potential energy. It has energy overall because it has mass, is in an environment with gravity, and is above the ground. These three factors multiplied will give you your potential energy.

The higher above the ground an object is, the greater its potential energy.
Potential Energy
its physics term for the fact that it is not in motion (kinetic energy) but it is above the ground, so at any moment it could "potentially" have kinetic energy by falling to the floor.
Referenced to the floor, 0.5 kg of mass 2 meters above it has(M) (g) (h) = (0.5) (9.8) (2) = 9.8 joulesof gravitational potential energy
The potential energy of a body of 1.0 kg mass 1.0 m above ground is 9.8 joules.
