2C electric charge Is displaced from a point of electric potential -20 V to some other point. The work done is 200 J, then electric potential of second point `V_(2)` = ........ volt.

A

60

B

80

C

180

D

220

Text Solution

Verified by Experts

`(W)/(Q) = V_(2)-V_(1)` [ But `V_(1)=-20 V ]`
`:. (200)/(2) = V_(2)- (-20)`
`:. 100 = V_(2) +20`
`:. V_(@) =80 ` Volt .
