Question

An electron is projected along the positive X - axis with an initial speed 3 × 10^6 m/s . It goes 0.45m and stops due to a uniform electric field in the region . Find the magnitude and direction of the field?

Answer 1

Answer:

Charged particles move in straight lines and accelerate (or decelerate) if projected into an electric field along the direction of the field. In an electric field the electron moves at a constant velocity at right angles to the field but accelerates along the direction of the field.
