-x2192- The effective electric field is zero as the electric field by any charge is cancelled by the diagonally opposite charge-x2192- E is a vector quantity

Four identical charges each of $1 μ C$ are placed at the corners of a square of side 10 cm. The resultant field strength at the centre is :
$18 \times 10^{5} V / m$
$9 \times 10^{9} V / m$
$3.6 \times 10^{5} V / m$
Zero

$\to$ The effective electric field is zero as the electric field by any charge is cancelled by the diagonally opposite charge.
$\to$ E is a vector quantity

Four identical charges each of 1μC are placed at the corners of a square of side 10 cm. The resultant field strength at the centre is :18×105V/m9×109V/m3.6×105V/mZero

→ The effective electric field is zero as the electric field by any charge is cancelled by the diagonally opposite charge.→ E is a vector quantity
