A dipole is placed in an electric field as shown. In which direction will it move?

Options

  1. Atowards the left as its potential energy will increase.
  2. Btowards the right as its potential energy will decrease.
  3. Ctoward, the left as its potential energy will decrease.
  4. Dtowards the right as its potential energy will increase.

Correct answer

B. towards the right as its potential energy will decrease.

Step-by-step solution

F 1 = q E 1 , F 2 = q E 2 E 1 > E 2 ⇒ F 1 > F 2 Hence, net force is towards right and its potential energy will decrease. Correction option is ( 2 )
