Charge on the element opposite to the gap isdq-Q2-x3C0-r-0-002-x3C0-

A charged ring of radius 0.5 m has 0.002 $π$ m gap. If the ring carries a charge of +1 C, the electric field at the center is :

$7.5 \times 10^{7} N C^{- 1}$
$7.2 \times 10^{7} N C^{- 1}$
$6.2 \times 10^{7} N C^{- 1}$
$6.5 \times 10^{7} N C^{- 1}$

Charge on the element opposite to the gap is
$d q = \frac{Q}{2 π r} (0.002 π)$

A charged ring of radius 0.5 m has 0.002 π m gap. If the ring carries a charge of +1 C, the electric field at the center is :7.5×107NC−17.2×107NC−16.2×107NC−16.5×107NC−1

Charge on the element opposite to the gap isdq=Q2πr(0.002π)
