When a body falls from an aeroplane there is increase in its: 1) acceleration 2) potential energy 3) Kinetic energy 4) Rest mass

When a proton is accelerated with IV potential difference, then its kinetic energy is:

When a proton is accelerated with 1 volt potential difference, then its kinetic energy is

When a proton is accelerated with 1 volt potential difference, then its kinetic energy is

The mass of an electron is m, its charge e and it is accelerated from rest through a potential difference V. The Kinetic energy of the electron in joules will be:

The mass of electron is M, its charge is e and it is accelerated from rest through a potential V. The kinetic energy of the electron will be :

A body (intially at rest is falling under gravity. When it loses a gravitational potential energy by U , its speed is v .The mass of the body shall be :
