Two parallel metal plates having charges +Q and -Q face each other...
Two parallel metal plates having charges and face each other at a certain distance between them. If the plates are now dipped in kerosene oil tank, the electric field between the plates will
Options
- Abecome zero
- Bincrease
- Cdecrease
- Dremain same
Correct answer
C. decrease
Step-by-step solution
The electric field in vacuum \begin{array}{rlrl} & & \mathrm{E}& =\frac{\sigma}{2 \varepsilon_0 \mathrm{k}}\\ \because & \mathrm{k}& >1 \\ \therefore & & \mathrm{E}& < \mathrm{E}}_{0} \end{array}
