An object start sliding on a frictionless inclined plane and from same height another object start falling freely.

Options

  1. Aboth will reach with same speed
  2. Bboth will reach with same acceleration
  3. Cboth will reach in same time
  4. DNone of the above

Correct answer

A. both will reach with same speed

Step-by-step solution

Here the potential energy will be converted to kinetic energy. Initially both the bodies have same potential energy. So finally both the bodies will have same kinetic energy. So they will reach the ground with same speed.
