Question

What is the direction of the net electric field at point P?

• A. $\hat{i}$
• B. $\hat{j}$
• C. $-\hat{i}$
• D. $-\hat{j}$

Answer 1

The correct option is A $\hat{i}$

The field on P due to upper and lower positive charge distribution is $E$ in the direction as shown which is symmetric about X-axis.

Hence the net field at P is $E_{net}$ which is along +ve X-axis.

$E_{net}$ is along $\hat{i}$.

Answer-(A)
