Question
If the electric flux entering and leaving a closed surface are respectively of magnitude φ1. and φ2, then the electric charge inside the surface will be :
Options
A.
B.(φ1 − φ2)ε0
C.ε0(φ2 − φ1)
D.ε0(φ2 + φ1)
Solution
Net flux = φ2 − φ2 = 
qin = ε0 (f2 − f1)
qin = ε0 (f2 − f1) Create a free account to view solution
