1. The wrong statement about electric lines of force is

1 point

These originate from positive charge and end on negative charge

They do not intersect each other at a point

They have the same form for a point charge and a sphere

They have physical existence

3. The figure shows some of the electric field lines corresponding to an electric field. The figure suggests

1 point

Ea > Eb > Ec

Ea = Eb = Ec

Ea = Ec > Eb

Ea = Ec < Eb

4. Figure shows the electric lines of force emerging from a charged body. If the electric field at A and B are Ea and Eb respectively, then

1 point

Ea > Eb

Eb > Ea

Ea = Eb
