Question

A circular ring of radius $r$ is placed in a homogenous magnetic field perpendicular to the plane of the ring. The field $B$ chnages with time according to the equation $B equals k t$ , where $k$ is a constant and $t$ is the time. The electric field in the ring is

$\frac{k r}{4}$
$\frac{k r}{3}$
$\frac{k r}{2}$
$\frac{k}{2 r}$

The correct answer is: $fraction numerator k r over denominator 2 end fraction$

$contour integral stack E with rightwards arrow on top bullet stack d l with rightwards arrow on top equals negative fraction numerator d ϕ B over denominator d t end fraction$
or $E cross times 2 pi r equals fraction numerator d over denominator d t end fraction open parentheses K t cross times pi r to the power of 2 end exponent close parentheses equals K pi r to the power of 2 end exponent$
or $E equals fraction numerator K r over denominator 2 end fraction$
