Q. Two identical positive charges are placed on the $y$ -axis at $y = - a$ and $y = + a$ . The variation of $V$ (electric potential) along $x$ -axis is shown by graph

$V = \frac{2 k q}{a ^{2} + x ^{2}}$

Q. Two identical positive charges are placed on the y-axis at y=−a and y=+a. The variation of V (electric potential) along x-axis is shown by graph

V=a2+x2​2kq​

Q. Two identical positive charges are placed on the $y$ -axis at $y = - a$ and $y = + a$ . The variation of $V$ (electric potential) along $x$ -axis is shown by graph
