voltage is energy per unit charge.
Energy gained = 2500 * charge on electron
= 2500 * 1.6*10^-19 Joules
(1/2) m v^2 = 2500 * 1.6*10^-19 Joules
where m = 9.1 * 10^-31 kg
Can someone please give me the formulas to solve these questions.
An election is accelerated by a voltage of 2500V between plates a and b. What’s the electrons change in energy when reaching plate b if it starts from rest. And what’s the electrons speed when reaching plate b ?
