Fig. shows the electric field lines arround three point charges A, B and C. In which region or regions of the picture could the electric field be zero? Justify your answer.

Sketch the electric lines of force due to point charges q > 0

Sketch the electric lines of force due to point charges q < 0

Show that the electric field due to a point charge is conservative?

Obtain expression for electric field due to a point charge

The two graphs drawn below show the variation electrostatic potential (V) with 1/r (r being distance of the field point from the point charge) for two point charges q_1 and q_2 . Which of the two charges has a larger magnitude and why?
