Answer 2

$\Large{\underline{\underline{\bf{Solution :}}}}$

The idea of electric lines of force or the electric field lines introduced by Michel Faraday is a way to visualize electrostatic field geometrically.

★ The properties of electric lines of force are the following:

• The electric lines of force are continuous curves in an electric field starting from a positively charged body and ending on a negatively charged body.

• The tangent to the curve at any point gives the direction of the electric field intensity at that point.

• Electric lines of force never intersect since if they cross at a point, electric field intensity at that point will have two directions, which is not possible.

• Electric lines of force do not pass but leave or end on a charged conductor normally. Suppose the lines of force are not perpendicular to the conductor surface. In this situation, the component of electric field parallel to the surface would cause the electrons to move and hence conductor will not remain equipotential which is absurd as in electrostatics conductor is an equipotential surface.

• The number of electric lines of force that originate from or terminate on a charge is proportional to the magnitude of the charge.

• As number of lines of force per unit area normal to the area at point represents magnitude of intensity, crowded lines represent strong field while distant lines weak field. Further, if the lines of force are equidistant straight lines, the filed is uniform.

Electric lines of force due to two equal positive charges (field is zero at O). O is a null point
