The electric field strength between two parallel conducting plates separated by $4\mathrm{.}60$ cm is $6\mathrm{.}30104$ V$/$m$.$

$($a$)$

What is the potential difference between the plates $($in kV$)?$

kV

$($b$)$

The plate with the lowest potential is taken to be at zero volts. What is the potential $($in V$)1\mathrm{.}10$ cm from that plate $($and $3\mathrm{.}50$ cm from the other$)?$

V
