Created by StemPy LabAssertion (A): If the net flux through a closed surface is zero, the electric field is zero at every point of the surface. Reason (R): The net flux through a closed surface depends only on the charge enclosed by it.

← Four statements about flux are given. (i) The net flux through a closed surface depends on the charges outside it. (ii) Gauss's law holds for every closed surface, but it gives the field only when the charges have a symmetry. (iii) The flux through a part of a closed surface can be negative. (iv) In a uniform field the net flux through any closed surface is zero. How many of the statements are correct?The field of a very long charged wire is 650 N/C at 12 cm from it. What is the field at 30 cm from it? →
