Question

The P.E.of a body at a certain height is 200J when it is released. The K.E when it just touches the surface is:

• A. Equal to potential energy
• B. Greater than potential energy
• C. Lesser than potential energy
• D. None of the above

Answer 1

The correct option is A Equal to potential energy

Initially the potential energy of the body is 200 J.
When it is released, its potential energy gets converted into kinetic energy.
When the body just touches the ground, the kinetic energy becomes equal to potential energy.
