in a cylinder capacitor with plate radii a and b, the potential difference between the plates is V. The electric field between the plates at a radial distance r from axis is1) V/ { R Ln (b/a)} 2) VLn (b/a)/ rand how.....?

electric field in a cylindrical capacitor is lambda/2*pi*Eo*r

E=Q*K/L*r

E=C*V*K/L*R

C=L*ln(b/a)*K

Put c

E=V*ln(b/a)/r
