What do electric lines of force (field lines) represent?

A metal sphere of radius R carrying q (+ve) charges is shown in the figure. br Draw the electric lines of force related to this metal sphere.

The electric lines of force never intersect one another - Explain this statement.

"The electric lines of force are discontinous with breaks". Check whether this statement is true or false.

Draw the electric lines of force surrounding the charges if. Br a .+ q charge and a .- q. charge are separated at a distance .a. apart in air.

Draw the electric lines of force surrounding the charges if. Br Two - q. charges are placed at a distance .a. apart in air.
