Fig shows the variation of electrostatic potential V with distance x for a given charge distribution.

From the points marked A,B and C, indentify the point at which electric field is (i) zero
(ii) maximum.
Explain your answer in each case.

Text Solution

Verified by Experts

As `E = - (dV)/(dx)` =n egative slope of V-x graph,
At A, `(dV)/(dx) = 0 , At B, (dV)/(dx) lt 0 , At C, (dV)/(dx) gt 0`
`:.` (i) E is zero at point A.
(ii) E is maximum at point B.
