Question

The electric field (E) between the plates of a charge cylindrical capacitor vary with distance (r) from the axis of the cylinder ? (A) E propto (1/r2) (B) E propto (1/r) (C) E propto r2 (D) E propto r

Electric field due to outer plate is zero so the electric field due to inner cylindrical charged conductor varies inversely as the distance from the axis.

Q. The electric field (E) between the plates of a charge cylindrical capacitor vary with distance (r) from the axis of the cylinder ?

$E \propto \frac{1}{r ^{2}}$

$E \propto \frac{1}{r}$

$E \propto r^{2}$

$E \propto r$

Q. The electric field (E) between the plates of a charge cylindrical capacitor vary with distance (r) from the axis of the cylinder ?

E∝r21​

E∝r1​

E∝r2

E∝r
