A solid metallic sphere has a charge +3Q.Concentric with this sphere is a conducting spherical shell having charge +Q.The radius of the sphere is a and that of the spherical shell is b,(b>a).What is the electric field at a distance R(a<R<b) from the centre- 1)Q/2pie0 2)3Q/2pie0 3)3Q/4pie0 4)4Q/2pie0 Share with your friends Share 20 Sanjay Singh answered this Dear student The electric field at the point is the ssum of the electric field due to both the charged spheres Electric field due to charge on the sphere isE1=14π∈3QR2and the electric field at the point due to charge on the spherical shell isE2=0So net electric field is Enet=14π∈3QR2Regards 32 View Full Answer Tarun Kumar answered this Pls no links 1
