If an electric dipole is placed in a non-uniform electric field ______ will act on the dipole.
A. A force but no torque
B. Both force and torque
C. Torque but no force
D. No torque or force
Answer:B
If an electric dipole is placed in a non-uniform electric field ______ will act on the dipole.
A. A force but no torque B. Both force and torque C. Torque but no force D. No torque or force
Explanation: In the case of a non-uniform electric field, the force acting on both the charges of the dipole will be unequal. So, there will be a net force acting on the dipole in a certain direction. Also, there will be a torque due to two forces acting at two different points. But in case of a uniform electric field, the net force on the dipole will be zero but net torque will be non-zero.
