A $10\mathrm{.}5-$cm$-$diameter parallel$-$plate capacitor has a $1\mathrm{.}9-$mm gap. The electric field between the plates is increasing at the rate

$1\mathrm{.}9$x$106$ V$/($m$-$s$).$

What is the magnetic field strength B between the plates of

he capacitor at a distance of $3\mathrm{.}7$ cm from the axis of

he capacitor?

B$=$

toward the wire. At that moment a switch is flipped, causing a current of $14\mathrm{.}1$ A to flow in the wire.

Find the magnitude of the electron's acceleration a at

that moment.
