Assertion (A): | \(\varepsilon_0\)). | The electric flux due to the external charge q and the induced charges on the sphere through the spherical surface S shown dotted in the diagram, is (-q/
Reason (R): | Negative charges are induced on the surface of the conducting sphere due to the positive charge q in the vicinity, and the potential of the conducting sphere is zero. |
