Find the fluz f the electric field through a spherical surface of radius R due to a charge of 10^(-7) Cat the centre and anotherequal charge at a point 2R away from the centre (figure ). |

Answer» Solution :Given: MAGNITUDE of the TWO charges placed = `( 10^-7)C` We know from Gauss's law that the FLUX experience by the sphere is only by due to internal CHARGE and not by the external ONE. Now, ` E xx ds = (Q/epsilon_0) = (10^-7)/ 8.85 xx (10^+12)` ` = 1.1 xx (10^4) N-m/C.` |
