Question

An electric dipole is placed at an alignment angle of 300 with an electric field of 2 * 10 ^ 6 * N * C . It experiences a torque equal |10 8 Nm. The charge on the dipole if the dipole ih = 1 cm *​

Answer 1

Answer:

Hint: We know that if we place a dipole in a uniform electric field, the dipole experiences a torque. The angle, dipole length and torque and electric field intensity are given. We can use these in the equation of torque to find the charge.
