Pick an option to check your answer.
Answer & Solution
Correct Answer
(A) (A)-(III), (B)-(II), (C)-(IV), (D)-(I)
Step-by-step Solution
Detailed explanation
Inside uniformly charged spherical shell, \(E=0\)
\(\therefore \mathrm{A} \rightarrow \mathrm{III}\)
For uniformly charged infinite plate
\(E=\frac{\sigma}{2 \varepsilon_0}\)
\(\therefore \mathrm{B} \rightarrow \mathrm{II}\)
Outside of spherical shell
\(E=\frac{Q}{4 \pi \varepsilon_0 r_2}=\frac{\sigma R^2}{\varepsilon_0 r^2}\)
\(\therefore \mathrm{C} \rightarrow \mathrm{IV}\)
Between two plates \(E=\frac{\sigma}{\varepsilon_0}\)
\(\therefore \mathrm{D} \rightarrow \mathrm{I}\)
\(\therefore \mathrm{A} \rightarrow \mathrm{III}\)
For uniformly charged infinite plate
\(E=\frac{\sigma}{2 \varepsilon_0}\)
\(\therefore \mathrm{B} \rightarrow \mathrm{II}\)
Outside of spherical shell

- If two glass plates have water between them and are separated by very small distance ( see figure), it is very difficult to pull them apart. It is because the water in between forms cylindrical surface on the side that gives rise to lower pressure in the water in comparison to atmosphere. If the radius of the cylindrical surface is \(R\) and surface tension of water is \(T\) then the pressure in water between the plates is lower by
