Problem
A charged particle having mass m is projected in a uniform electric field with a kinetic energy K0. After time t0 it was observed that the kinetic energy of the particle was 4K0 and its velocity was perpendicular to the field.
- How much more time is required for the particle to regain its lost kinetic energy?
- Write the impulse of the electric force acting on the particle between the two points where its kinetic energy is K0.
Neglect all other forces on the particle apart from the electrostatic force.
