Explanation:
Relation between work and change in kinetic energy is as follows.
Also,
= J
= J
Let us assume that electric force on the electron has a magnitude F. The electron moves at a distance of 0.3 m opposite to the direction of the force so that work done is as follows.
w = -Fd
F =
Therefore, relation between electric field and force is as follows.
E =
=
= C
Thus, we can conclude that magnitude of the electric field that will stop these electrons in a distance of 0.3 m is C.
