Hi Mostafijur,

Let the inner sphere has a charge +Q
outer sphere -Q
then
between the sphere we have

Thanks & Regards

Hello Student

Let potential of the plate of radius a
Q = CV
V = Q/C
E = KQ/r2
V = KQ(b−a)/ab
Q = Vab/K(b−a)
E = (K/r2)(Vab/K(b−a)) = abV/r2(b−a)

I hope this answer will help you.
