Answer: 3 times as much the potential energy
Explanation:
Potential energy is the energy possessed by an object by virtue of its position.

m= mass of object
g = acceleration due to gravity
h = height of an object
When same object with same is lifted from 10 feet to 30 feet. The height has increased 3 times , thus the potential energy will also get 3 times as much.
The electromagnet and the permanent magnet -- interact with each other as any two magnets do. The positive end of the electromagnet is attracted to the negative pole of the permanent magnetic field, and the negative pole of the electromagnet is repelled by the permanent magnet's negative pole
