Question

what happens to potential energy if-
  1. mass of object is tripled. find the potential energy gained by the boy.
  2. object is lowered to half of its original height.
  3. the object is taken from poles to equator.

Solution

POtential energy is given by:PE = mghas mass increases to three times then potential energy becomes three times.gain = final - initial gain = 3mgh -mgh = 2mghwhen height decreases to half of the value then PE decreases to half of the initial value.When we move from pole to equator, g decreases therefore PE decreases.
