From the equation , Delta = k xx 1000/C ...

From the equation , `Delta = k xx 1000/C ` , we see `Delta prop 1/C` Comment on the validity of the last relation .

Text Solution

Verified by Experts

For the relation , `Delta prop 1/C` to be valid , `k xx 1000` must be a constant . But k varies with C . If C varies `(k xx1000)` cannot remain constant . So , `Delta` connot be inversely proportional to C . Therefore, the relation `Delta prop 1/C` is erroneous
