The electric field on a capacitor is given by:
[tex]E=\frac{V}{d}[/tex]where d is the distance between the plates and V is the voltage in the capacitor. In this case, the voltage is 62 V and the distance is 0.036 m; plugging these values we have:
[tex]E=\frac{62}{0.036}=1722.22[/tex]Therefore, the electric field i 1722.322 V/m
