# Q. Two metal plates are separated by 2 cm. The potentials of the plates are − 10 V and + 30 V. The electric field between the two plates is

KCET KCET 2019

Solution:

## $\quad E=\frac{V}{\alpha}=\frac{30-\left(-10\right)}{2\times10^{-2}}=2000 V m^{-1}\quad\left(\alpha=distance\, between \,two\, plates\right)\quad$
