Capacitance of capacitor is c ,p.d.is v
consider initial charge be Q′ charge given to plate Q
total charge on+ve plate will be Q′+Q
potential difference now= (E'+E)d
E= electric field due to positive plate= Q+Q′/2εA
E'= electric field due to negetive plate=Q/2εA
so potential difference=(E+E')d
on solving we get V'=Q/2C+V
