Question

40 coulombs of charge is brought from infinity to a point in an electric field when 60 joules of work is done. What is the potential at that point

Answer 1

Answer:

1.5V

Explanation:

Given: W=60 J

C=40c

we know that,

Potential=workdone/charge

V=w/c

V = 60/40

=1.5volts

Answer 2

GIVEN -

       CHARGE : 40 coulombs

       WORK DONE : 60 joules

TO FIND -

           POTENTIAL : ?

SOLUTION

         W = V * Q

          V = W / Q

          V = 60 / 40

          V = 3 / 2

          V = 1.5 Volts
