Answer:
E = 4.78*10^6 N/C
Explanation:
In this case you have to take into account that both magnetic force and electric force must be equal


However, you have to know first what is the speed of the electron by using the expression for the kinetic energy (1keV=1000*1.6*10^{-19}J):

by replacing in the expression for the forces you have
