What is the potential energy of a 20 mg raindrop at an altitude of 2 km?

What is the potential energy of a 20 mg raindrop at an altitude of 2 km? Consider that zero potential energy corresponds to the position of the drop at the earth’s surface.

To find out the potential energy of the specified raindrop, we use the formula: Ep = mk * g * h.

Const: q – acceleration of gravity (since h «Rz (radius of the Earth), then we can take q ≈ 10 m / s2).

Data: mk is the mass of a raindrop (mk = 20 mg = 2 * 10 ^ -5 kg); h – drop height (h = 2 km = 2 * 10 ^ 3 m).

Let’s perform the calculation: Ep = mk * g * h = 2 * 10 ^ -5 * 10 * 2 * 10 ^ 3 = 0.4 J.

Answer: The potential energy of the specified raindrop is 0.4 J.
