Calculate the electrostatic force acting on a proton when it is placed in a uniform electric filed of `3.2 xx 10^4 NC^-1`.

Two charges +3muC and -3muC are separated by a very small distance of 5mm. Br If the above arrangement is placed in a uniform electric field of intensity 3x10^-5 N/C with its axis perpendicular to the field direction. What is the torque acting on it?

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 dipole consisting of an electron and a proton separated by a distance 4xx10^(-10)m is situated in an electric field of intensity 3xx10^5NC^(-1) at an angle of 30^@ with the field. Calculate the dipole moment and torque acting on it.
