Question

An electric dipole is placed at an angle of 30° to a non-uniform electric field. The dipole will experience : (A) a translational force only in the direction of the field (B) a translational force only in a direction normal to the direction of the field (C) a torque as well as a translational force (D) a torque only

In a non-uniform electric field, the dipole may experience both non-zero torque as well as translational force.
For example as shown in figure.

F 1^{*} F 2

as

E

is non-uniform.
Torque would also be non-zero.

Q. An electric dipole is placed at an angle of 30° to a non-uniform electric field. The dipole will experience :

a translational force only in the direction of the field

a translational force only in a direction normal to the direction of the field

a torque as well as a translational force

a torque only

In a non-uniform electric field, the dipole may experience both non-zero torque as well as translational force. For example as shown in figure. F1∗F2 as E is non-uniform. Torque would also be non-zero.

Q. An electric dipole is placed at an angle of $3 0^{°}$ to a non-uniform electric field. The dipole will experience :

In a non-uniform electric field, the dipole may experience both non-zero torque as well as translational force.
For example as shown in figure. $F 1^{*} F 2$ as $E$ is non-uniform.
Torque would also be non-zero.
