Question

Figure shows three point charges +2q, –q and +3q. Two charges

+2q and –q are enclosed within a surface ‘S’. What is the electric

flux due to this configuration through the surface ‘S’?

5. The power factor of an a.c. circuit is 0.5. What will be the phase difference between voltage

and current in this circuit?​

Answer 1

Answer:

Explanation:net enclosed charge= +2q - q = +q

electric flux= net charge / ε

= q/ε
