Triboelectric effect and charge. Consider the charge q is placed at the centre of face ADHE of the cube shown below in the figure, Because of the location of the field point $\boldsymbol{E}=E(-\boldsymbol{i})$, Due to symmetry all force due to charges cancel each other at centre, Electric field inside the conductor is zero as electron move in such a way in the conductor so as to nullify any electric field produced by the charge, (A)The force with which two charges interact is not changed by the presence of the other charges: it is correct we know this from coulomb law. These are the basic set of questions you must do in order to get good understanding of the subject and get good marks. Rapid chargers can charge at 50kW, while ultra-rapid chargers charge at around 150kW, with some getting as high as 350kW, so it’s much quicker than charging at home. We know that electric field inside the conductor is zero as electron move in such a way in the conductor so as to nullify any electric field produced by the charge Now since no electric field is there inside the sphere, flux through a spherical surface inside the sphere must be zero.
