Question
There exists a non-uniform electric field along x-axis as shown in the figure below. The field increases at a uniform rate along +ve x-axis. A dipole is placed the field as shown. Which on the following is correct for the dipole?
Options
A.Dipole move along positive x-axis and undergoes a clockwise rotation
B.Dipole move along negative x-axis and undergoes a clockwise rotation
C.Dipole move along positive x-axis and undergoes a anticlockwise rotation
D.Dipole move along negative x-axis and undergoes a anticlockwise rotation
Solution
The dipole is placed in a non -uniform field, therefore a force as well as a couple acts on it. The force on the negative charge is move (F ∝ E) and is directed along negative axis. Thus the dipole move along negative x-axis and rotates in an anticlockwise direction
