A dipole of dipole moment p → = p i ^ lies along the x -axis in a non-uniform electric field E → = c x i ^ . The force acting on the dipole is

Options

  1. Azero
  2. B- p c x 2 i ^
  3. Cp c x 2 i ^
  4. D- p c 2 x 2 i ^

Correct answer

B. - p c x 2 i ^

Step-by-step solution

The force acting on a dipole is F → = p → ∂ E x ∂ x F → = p → d d x c x = - p c x 2 i ^
