An electron is accelerated through a potential difference of 400 V. The electron

Question

An electron is accelerated through a potential difference of 400 V. The electron gains a genetic energy of 6.4 times 10^-17 J if it passes from the negative to the positive terminal of the accelerator. 6.4 times 10^-17 J if it passes from the positive to the negative terminal of the accelerator. 4 times 10^2 J if it passes from the negative to the positive terminal of the accelerator. times 10^2 .1 if it passes from the positive to the negative terminal of the accelerator. 6.4 times 10^2 .1 if it passes from the positive to the negative terminal of the accelerator.

Explanation / Answer

V = 400 V
KE = e*V = 1.6*10^-19*400 = 6.4*10^-17 J , s o o p t i on A
