Question A beam of electrons moving at a speed of 2.8 × 10^7 ms−1passes through perpendicular electric andmagnetic fields without being deflected. The magnetic field has a flux density 3.2 × 10^−3 T.Calculate the strength of the electric field.
So I thought Electric field force = magnetic field force so for magnetic field: F=Bev F= (3.2 × 10^−3) * (1.60× 10^−19) * (2.8 × 10^7) F= 1.4 × 10^−14
What am I doing wrong, I know it must be something dumb.
