The figure shows two parallel plates. The graph indicates the potential at points between the two plates, with V$2=20$ ?V at x$2=0\mathrm{.}4$ ?m and V$1=15$ ?V at x$1=0\mathrm{.}3$ ?m$.$ ?An electron is released from

rest at x$1,$ ?and that release point and the plate locations are aligned with the graph.

A$.)$ ?What is the magnitude of the electric field between the plates? 

B$.)$ ?If the electron is released from rest, what is its speed$($in m$/$s$)$ ?just as it runs into the plate?
