Two large horizontal, parallel metal plates are 2.0 cm apart in air and the upper plate is maintained at a positive potential relative to the lower plate so that field strength between them is 2.5×105 Vm-1. An electron is released from rest at the lower plate. What is its speed on reaching the upper plate?

[e=1.6×10-19C;me=9.1×10-31kg]
