Answer:
the height at which the object is with respect to the ground is 4 meter.
Explanation:
Given,
An object of mass 6 kg is at a certain height above the ground. the
potential energy of the object is 240 J.
To find: the height at which the object is with respect to the ground.
Solution:
Potential energy is defined as the energy possessed by body by virtue of position and configuration.
or, P.E = mgh
here, m = 6 kg, P.E = 240 J , g = 10 m/s^2
Substituting the values,
240 = 6 * 10 * h
or, h = 240 / 60
or, h = 4 m
Therefore, the height at which the object is with respect to the ground is 4 meter.

Given
- Mass (m) = 6 Kg
- Potential energy (P.E) = 240 J
- Acceleration due to gravity (g) = 10 m/s
To find
- Height (h)
Solution
- P.E = mgh
Substituting we get :-
- 240 = (6)(10)(h)
- 240 = 60h
- h = 240/60
- h = 24/6
- h = 4
Hence, the height at which the object is with respect to the ground is 4 m
