1.Why do the electric field lines not form closed loops ? 2. Does the charge given to a metallic sphere depend on whether it is hollow or solid? 3. Draw the pattern of electric fields lines , when a point charge -Q is kept near an uncharged conducting plate ? 4. what is electric flux through a cube of one side which enclosed an electric dipole ? 5. Two metallic spheres A and B kept on insutating stands are in contact with each other . A positively charged rod p is brought near the sphere A as show in figure . the two spheres are seperated from each other , and the rod p is removed . what will be nature of charges on spheres A and B ? 6. two charges of magnitudes -2q and +q are located at points (a,0) and (4a,0 ) respectively . what is electric flux due to charges when we take a sphere of radius 3a at the origin ? 7. A metal sphere is kept on an insulating stand . A negatively charged rod is brought near it , then the spheres is earthed . on removing the ear...
