A resistance of `50Omega` is registered when two electrodes are suspended into a beaker containing a dilute solution of a strong electrolyte such that exactly half of them are submerged into solution as shown in figure. If the solution is diluted by adding pure water (negligible conductivity) so as to just completely submerge the electrodes, the new ressitance offered by the solution would be: ltbegt

A

`50 Omega`

B

`100 Omega`

C

`25 Omega`

D

`200 Omega`

Text Solution

Verified by Experts

The correct Answer is:
A
`R=1/k l/A`
The k is halved while the A is doubled.Hence R remains `50 Omega`.
