Question

work done to take an electron from rest where potential is -60 v to the another point where potential is-20v is given by
A)40eV
B)-40eV
C)60eV
D)-60eV
​

Answer 1

ANSWER: OPTION B

GIVEN : V1= -60V

V2= -20V

WORK DONE = (DELTA V)e

                      =(V1 - V2)e

                      =[(-60)-(-20)]e

                      = -40eV
