A body having a mass of 4.5kg is supported 30kg above earth surface calculate the portential energy take 10kg?

The given units are incorrect.

To calculate the potential energy of an object, we need to use the formula:

Potential Energy = mass * gravity * height

Given:
Mass of the body (m) = 4.5 kg
Height above the ground (h) = 30 m
Acceleration due to gravity (g) = 10 m/s²

Substituting these values into the formula, we get:

Potential Energy = 4.5 kg * 10 m/s² * 30 m

Now, let's calculate the potential energy step by step:

Step 1: Multiply the mass by gravity:
4.5 kg * 10 m/s² = 45 N

Step 2: Multiply the result by the height:
45 N * 30 m = 1350 Joules

Therefore, the potential energy of the body when it is 30 meters above the Earth's surface and has a mass of 4.5 kg is 1350 Joules.
