Question 27: NCERT Class 12th Physics: Chapter 1 – Electric Charges And Fields

In a certain region of space, electric field is along the z-direction throughout. The magnitude of electric field is, however, not constant but increases uniformly along the positive z-direction, at the rate of 105 N C-1 per metre. What are the force and torque experienced by a system having a total dipole moment equal to 10-7 C m in the negative z-direction?

  1. Solution:
    As electric field increases in positive z-direction from A to B, So

    directed in direction of FB i.e., from B to A or along -z direction.
    As the two forces on charges of electric dipole are collinear and opposite, so net torque on it is equal to zero.
