12 Physics Electrostatic Potential And Capacitance - Set No : 3 Question No :9
Question No : 9
| Consider the charge configuration and a spherical Gaussian surface as shown in the figure. When calculating the flux of the electric field over the spherical surface, the electric field will be due to |
| a) |  | b) | Only the positive charge |
| c) | All the charges | d) |  |
Answer No : 9
(c)Electric
flux may be due to the charges present inside the Gaussian surface, but for
the purpose of calculation of electric field  at any point we shall have to
consider contribution of all the charges. |
