Question

if a non uniform electric - field varying as 3r^2 N/C , find the potential difference between two point located at 1,0 and 6,0

Ans ∆215v​

Answer 1

Answer:The total work done = energy transferred.so, we might see the equation energy = voltage x charge, E = V * Q, written as, work = voltage x charge, W = V * Q.In this case, the charge is 4 mC, that is, 0.004 C and work done is 2 J.Therefore, V=W/Q = 2/0.004 = 500 V.Hence, the potential difference between two points if 2 J of work must be done to move a 4 mC charge from one point to another is 500 V.
