The variation of electric potential with distance from a fixed point is shown in figure. What is the value of electric field at \(x=2 \mathrm{~m}\) ?
- A 0
- B 3
- C 2
- D 6
Answer & Solution
Correct Answer
(A) 0
Step-by-step Solution
Detailed explanation
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 \(C\) ) \(E=\frac{-d V}{d x}=0 \quad[\because V=\text { constant }]\)
