- Potential energy: The energy of an object due to its position is called potential energy. It is denoted by PE.
- Mathematically potential energy can be written as
- P.E of object = m g h
Where m = mass of an object, g = acceleration due to gravity, and h = height
CALCULATION:
We are given,
m = 1 kg, g = 10 m/s2, h = 5 metres
PE = 1 × 10 × 5 = 50 J
Hence option 1 is correct.
