PhysicsEasysingle choice

A uniform but time-varying magnetic field exists in the cylindrical region and directed into the paper. If field decrease with time and a positive charge placed at any point inside the region, then it moves

Options:

Answer:

Solution:

$\int E . d l = - π r^{2} \frac{d B}{d t}$

$E \times 2 π r = + π r^{2} \times \frac{d B}{d t} (a s \frac{d B}{d t} = - v e)$

$E = + v e$

$∴$ assume direction is right

so $q$ charge move along 4
