The electric field is E-x2212-dVdxAt 1 and 2- V-0 So the electric filed at 1 and 2 may be zero-At 3- V is maximum- so dVdx-0- thus the electric field must be zero at 3-

Two point charges are kept at a certain distance from one another. Figure represents the variation of the potential along the straight line connecting the two charges. At what point is the electric field zero?

$1$
$2$
$3$
All of these

The electric field is $E = - \frac{d V}{d x}$
At $1$ and $2$ , $V = 0$ So the electric filed at $1$ and $2$ may be zero.
At $3$ , V is maximum, so $\frac{d V}{d x} = 0$ , thus the electric field must be zero at $3$ .

The electric field is E=−dVdxAt 1 and 2, V=0 So the electric filed at 1 and 2 may be zero.At 3, V is maximum, so dVdx=0, thus the electric field must be zero at 3.
