Question

(a) Calculate the electric potential 0.300 cm from an electron. 4.794X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. V (b) What is the magnitude of the electric potential difference between two points that are 0.300 cm and 0.760 cm from an electron? 1.892X The response you submitted has the wrong sign.V (c) How would the answers change if the electron were replaced with a proton? O The sign of answer (a) would change. O The sign of answer (b) would change. The sign of both answers would change O Both answers would remain the same

Answer 1

A)

Potential, V1 = (9 x 10^9)(-1.6 x 10^-19)/(0.3 x 10^-2)

V1 = - 4.8 x 10^-7 V

B)

V2 = (9 x 10^9)(-1.6 x 10^-19)/(0.76 x 10^-2)

V2 = - 1.89 x 10^-7 V

dV = V2 - V1 = 2.91 x 10^-7 V

C)

Sign of answer (a) would change
