Question

Four electrical charges are arranged on the corners of a 10 cm square as shown What would be the direction of the resulting electric field the center point P-leftarrowrightarrowuparrowdownarrow

Toppr Admin · Accepted Answer

Electric field at P due to a positive charge 0 $Q$ at corner= $F = \frac{Q}{4 π ϵ_{o} r^{2}}$ where $r$ = distance between corner and P

The direction of field and the resultant field are shown in figure.

Hence, the resultant field at $P = \sqrt{2} F$ bisecting the two F vectors shown in 2nd figure .

Hence, field is in vertically upward direction $(↑)$ .
