Which of the following Maxwell’s equation is valid for time varying conditions but not valid for static conditions:

An electron is released from the origin at a place where a uniform electric field $E$ and a uniform magnetic field $B$ exist along the negative $y$-axis and the negative $z$-axis respectively. Find the displacement of the electron along the $y$-axis when its velocity becomes perpendicular to the electric field for the first time.

Identify the incorrect Maxwell's equation out of the following options.

A thin non-conducting ring of mass $m$, radius $a$ carrying a charge $q$ can rotate freely about its own axis which is vertical. At the initial moment, the ring was at rest in horizontal position and no magnetic field was present. At instant $t=0$, a uniform magnetic field is switched on which is vertically downward and increase with time according to the law $B=B_{0}t$. Neglecting magnetism induced due to rotational motion of ring.
