Can we create an electric field in which all the lines of force are parallel but their density increases continusously in a direction per-pendicular to the lines of force, fig.
,

For a unifrom electric field the lines of forces are

Represent a uniform electric field using lines of force.

Work done to move a charge along a closed path inside an electric field is always zero. Use this fact to prove that it is impossible to produce an electric field in which all the lines of force would be parallel straight lines and the density of their distribution would constantly increase in a direction perpendicular to the lines of force as shown in Figure.​

If a charge is released in electric field, will it follow lines of force ?

If a charge is released in electric field, will it follow lines of force ?

If electric field is uniform, then the electric lines of forces are :

If electric field is uniform, then the electric lines of forces are :

Draw the lines of force to represent a uniform electric field.
