12 j of work has to be done against an existion electric field to take a charge of 0.01 C from A to B. How much is th potential difference `V_B - V_A?`

Text Solution

Verified by Experts

Now,` v_b-v_a=potential difference=? Charge=0.01C,`
` work done =12J `
Now, work done=potential differencexxcharge
` pot. Difference=12/0.01=1200volt.`
