JEE Mains · Physics · STD 12 - 2. Electric potential and capacitance
Two charged conducting spheres of radii \(a\) and \(b\) are connected to each other by a conducting wire. The ratio of charges of the two spheres respectively is _______.
- A \(\sqrt{\mathrm{ab}}\)
- B \(a b\)
- C \(\frac{a}{b}\)
- D \(\frac{\mathrm{b}}{\mathrm{a}}\)
Answer & Solution
Correct Answer
(C) \(\frac{a}{b}\)
Step-by-step Solution
Detailed explanation
Potential at surface will be same \(\frac{\mathrm{Kq}_1}{\mathrm{a}}=\frac{\mathrm{Kq}}{\mathrm{b}}\) \(\frac{\mathrm{q}_1}{\mathrm{q}_2}=\frac{\mathrm{a}}{\mathrm{b}}\)

- Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : With the increase in the pressure of an ideal gas, the volume falls off more rapidly in an isothermal process in comparison to the adiabatic process.
Reason (R) : In isothermal process, \(\mathrm{PV}=\) constant, while in adiabatic process \(\mathrm{PV}^\gamma=\) constant. Here \(\gamma\) is the ratio of specific heats, P is the pressure and V is the volume of the ideal gas.
