Question

a potential difference of 0.3v is applied between two plates separated by a distance of 1mm . find electric intensity in the region between the plates

Answer 1

Answer:

Explanation: we know that,

                E=dv/dr

            using this relation,

            E=dv/dr

           intigrate with respect to r, we get

           E=dv* 1/r

       now,

           E=0.3/0.001   v/m

           E=300 v/m
