| The potential at any observation point P of a static electric field is defined as the work done by the external agent (or negative of work done by electrostatic field) in slowly bringing a unit positive point charge from infinity to the observation point. Figure shows the potential variation along the line of charges. Two point charges \[{{Q}_{1}}\], and \[{{Q}_{2}}\]lie along a line at a distance from each other. |

| Read the given passage carefully and give the answer of the following questions. |
A) 1
B) 2
C) 3
D) Both (a) and
Correct Answer: C
Solution :
(c) 3 As\[\frac{-dV}{dr}={{E}_{r}}\], the negative of the slope of V versus r curve represents the components of electric field along r. Slope of curve is zero only at point 3. Therefore, the electric field vector is zero at point 3.
