raketka [301]

Answer:

E=3.22*10^6 N/C

Explanation:

From the question we are told that:

Separation Distance d=1.0cm =0.01m

Potential difference V=3.22 * 10^4 V

Generally the equation for Electric Field strength is mathematically given by

 E=\frac{v}{d}

 E=\frac{3.22*10^4}{0.01}

 E=3.22*10^6 N/C
