if the radius of circular capacitor plates is doubled,the c of capacitor will increase by a factor of 4.explain

Expert Answer
Dear student,
Capacitance = ε A / d
Here, in case of circular plates, A = pi r^2
Hence, we see that c is proportional to square of r
so, if r is doubles, C increases by 4 times.
Hope this helps.
Thanking you
