Represent a uniform electric field using lines of force.

An electric dipole placed in an electric field experiences a torque. When a dipole is placed in a uniform electric field the torque acting on it is found to be 0.707 times the maximum torque. Calculate the angle between the Intensity of electric fied and electric dipole moment and draw the orientation of the dipole in the electric field.

A small metal ball is suspended in a uniform electric field with the help of an insulated thread. If high energy X-ray beam fall on it
