The variation of electric potential with distance from a fixed point is shown in figure. What is the value of electric field at \(x=2 \mathrm{~m}\) ?
0
3
2
6
Solution
According to given diagram, potential is constant in region \(A B\).
i.e., \(\quad V=\) constant
\(\therefore\) Electric field at \(x=2 \mathrm{~m}\) (at point \(C\) )
\(E=\frac{-d V}{d x}=0 \quad[\because V=\text { constant }]\)
