An electron, travelling at 2.3x10 m/s, enters perpendicular to the electric field between two horizontal charged parallel plates. If the electric field strength is
1.5x102 V/m, calculate the time taken for the electron to deflect a distance of
1.0x102m toward the positive plate. ​

the answer is b, have negligible mass
