Question A thin spherical conducting shell of radius \( \mathrm{R} \) has a charge q. Another charge \( \mathrm{Q} \) is placed at the centre of the shell. The electrostatic potential at a point \( \mathrm{P} \) a distance \( \mathrm{R} / 2 \) from the centre of the shell is.
(A) \( \quad \frac{(q+Q)}{4 \pi \varepsilon_{0}} \frac{2}{R} \)
(B) \( \frac{2 Q}{4 \pi \varepsilon_{0} R} \)
(C) \( \quad \frac{2 Q}{4 \pi \varepsilon_{0} R}-\frac{2 q}{4 \pi \varepsilon_{0} R} \)
(D) \( \frac{2 Q}{4 \pi \varepsilon_{0} R}+\frac{q}{4 \pi \varepsilon_{0} R} \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
