A solid conducting sphere of radius \( a \) has a net positive charge 2Q. A conducting spherical shell of inner radius \( b \) and outer radius \( c \) is concentric with the solid sphere and has a net charge \( -Q \). The surface charge density on the inner and outer surfaces of the spherical shell will be strong                                                                                                                                                                   [AMU 2002]/strong   (a) \( -\frac{2 Q}{4 \pi b^{2}}, \frac{Q}{4 \pi c^{2}} \)                                                                               (b) \( -\frac{Q}{4 \pi b^{2}}, \frac{Q}{4 \pi c^{2}} \)   (c) \( 0, \frac{Q}{4 \pi c^{2}} \)                                                                                     (d) None of the above 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
