The magnetic field in a certain cylindrical region is changing with time according to the law $B = [16 - 4 t^{2}]$ Tesla. The magnitude of induced electric field (Volt/meter) at point P at time $t = 2 sec$ is

Answer:

8.00

Solution:

Ans (8.00)

$E = \frac{r}{2} \frac{d B}{d t} = \frac{1}{2} [- 8 t] = - 4 t = 8$
