Question

Inside a particular cathode ray tube, there is a uniform electric field with a magnitude 423 N/C pointing in the positive x-direction. An electron, initially at rest, moves a distance of 3.50 cm in this field. (a) How much work (in J) does the electric field do on the electron?

Step 1

The work \( W \) done by an electric field on a charge \( q \) when it moves a distance \( d \) in the direction of the field is given by the formula: \[ W = qEd \] where \( E \) is the magnitude of the electric field. Show more…
