q_1, q_2, q_3and q_4 are point charges located at points as shown in the figure and S is a spherical Gaussian surface of radius R. Which of the s following is true according to the Gauss's law

Answer»

`OINT (VEC(E_1) + vec(E_2) + vec(E_3)) .d vec(A) = (q_1 + q_2 + q_3)/(2epsilon_0)` 
`oint (vec(E_1) + vec(E_2) + vec(E_3)) .d vec(A) = ((q_1 + q_2 + q_3))/(epsilon_0)` 
`oint (vec(E_1) + vec(E_2) + vec(E_3)) .d vec(A) = ((q_1 + q_2 + q_3 + q_4))/(epsilon_0)` 
NONE of the above
