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

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 lines of force to represent a uniform electric field.

Two equal and opposite charge +q and -q are separated by a small distance 2a. Br Name this arrangement.

Gauss.s theorem is useful in determining the elec tric field when the source distribution has symmetry. Br a) The electric field intensity at a distance .r. from a uniformly charged infinite plane sheet of charge is br br

Electric field is an important way of characterising the electrical environment of a system of charges. Two point charges q, and q, of magnitude +10 C and-10C respectively are placed 0.1 m apart. Calculate the electric fields at points A, B and C shown in the figure.

Draw the electric field lines and equipotential surface for a single positive point charge.
