The electric field strength between two parallel conducting plates separated by $4\mathrm{.}00$ cm is $6\mathrm{.}25104$ V$/$m$.$ Part $($a$)$ What is the potential difference, in volts, between the parallel conducting plates? V $=2500.$ V $$Correct$!$ Part $($b$)$ The electric potential of the lower$-$potential plate is defined as zero volts. What is the value of the electric potential, in volts, at a point in the gap between the plates that is $2\mathrm{.}5$ cm from the zero$-$volt plate? V $=$
