Question
If a body of mass 1 kg is at a height 1 m, find gravitational potential energy with respect to earth (g =10m/s2).
- 10
- 20
- 30
- 40
Hint:
U= mgh. If a body of mass 1 kg is at a height of 1 m, gravitational potential energy with respect to earth (g =10m/s2) will be 10J.
The correct answer is: 10
- The formula for gravitational potential energy is U= mgh.
- In this case, a body of mass 1 kg is kept at a height of 1 m.
- Therefore, gravitational potential energy is given as 1×10×1 = 10 J.
- So, the correct option is a.
