Question

Two negative charges of equal magnitude are located in $x-y$ plane as shown below in the figure. The direction of the electric field at point $P$ is

• A. along positive - $x$ direction
• B. along negative $-x$ direction
• C. along positive - $y$ direction
• D. along negative - $y$ direction

Answer 1

Answer: (B)

As $E_1=E_2$ and charges are symmetrically placed on $Y$-axis,

Resultant lies along angle bisector of $E_1$ and $E_2.$
i.e., along negative $X-$ axis.
