An electron with a velocity of v= (3x+ 4y+ 2z) × 106 m/s enters a region where there is both a magnetic field and an electric field. The magnetic field is B = (1x- 2y+ 4z)T. If the electron experiences no force as it moves, calculate the electric field.
force of electric field is F=Eq
for of magnetic field is F=qV*B
