Question

In the figure below, a point charge + Q1 is at the center of a spherical Gaussian surface S, and another point charge + Q2 is outside it. Point P is on the surface of S. Let Phis be the net electric flux through S, and let be the electric field at point P on S. Which one of the following statements is true? Both charges + Q1 and + Q2 make nonzero contributions to Phis but only the charge + Q1 makes a nonzero contribution to Both charges + Q1 and + Q2 make nonzero contributions to Phis but only the charge + Q2 makes a nonzero contribution to Only the charge + Q1 makes a nonzero contribution to Phis but both charges + Q1 and + Q2 make nonzero contributions to Charge + Q1 makes no contribution to Phis or Charge + Q2 makes no contribution to Phis or

Explanation / Answer

Flux depends only on Q1 Electric field is dependant on Q1 and Q2 SO C
