# what is the potential energy at centre of capacitor ;is it  zero then why a charge particle get accelerated when we place it at that point ?is conservation of energy holds good here?

Hi
Actually its not zero
field between the capacitor is
$\vec E=\frac{\sigma}{\epsilon_0}\widehat n \\where \widehat n is the directional unit vector from positive to negative plate \\so V=E.dn\neq 0$
