Question

How much work will done in bring a charge of 3×10¯¹²c from infinite to a point p at which the potential is 20v

Answer 1

Heya mate here is your answer :-

V=W/Q

20V=W/3×10^-12C

W=60×10^-12J

Hope it helps

Answer:

60 ×10¯¹² J work will done in bring a charge of 3×10¯¹²c from infinite to a point p at which the potential is 20V.

Solution:

Given,

Q = 3×10¯¹² C

V = 20V

By using the formula of Potential difference.

V = W/Q

Now, putting the value of given values.

20 = W / 3×10¯¹² C

=> 20 × 3×10¯¹² C = W

=> W = 20 × 3×10¯¹² J

=> W = 60 ×10¯¹² J

.°. W = 60 ×10¯¹² J
