An uncharged metallic sphere of radius r is placed into an external uniform field, as a result of which an induced charge appears on the sphere with surface density = o cos, where o is a positive constant and is a polar angle. Chapter 4: Laws of Thermodynamics. If two conductors are brought into contact, the charges from one of them will flow over to the other until their potentials become equal.
Electrostatics Force Discharge Potential Notes Class 12 Pdf Downl A similar experiment using a nylon thread or a rubber band yielded no charge transfer from the plastic rod to the pith ball. in metals induced charge is equal and opposite to inducing charge. Main Previous Year papers, JEE A point charge q is within an electrically neutral shell whose outer surface has spherical shape. Physics Wallah - Alakh Pandey.

Notes for class 7, Ask Inside the conductor, the electrons distribute themselves in such a way that the final electric field at all points inside the conductor is zero. The electrostatic field is zero inside a conductor In the static condition, whether a conductor is neutral or charged, the electric field inside the conductor is zero everywhere. The outside (valence) electrons of metal separate from their atoms and become free to move. Education, West Bengal wise Class 8 Math's Quiz, Chapter wise We can conveniently label one of these charges, Q a source charge and label q, as a test charge. Botany Notes, NCERT (a) This is because the comb gets charged by friction.
