1.	Fig shows a closed surface surrounding some electric charges (a) what is the net electric flux through the surface? (b) Is the electric flux directed inward or outward from the surface ?
Answer» (a) Here, total charge inside the surface : `q = -6.7 muC + 3.2 muC = -3.5 muC` As `phi_(E) = (q)/(in_(0)) = (-3.5xx10^(-6))/(8.85xx10^(-12))` `= -3.95xx10^(5) Nm^(2) C^(-1)` (b) As `phi_(e)` is negative, it is directed Inwards.
