D. No torque or force
Answer:C
If an electric dipole is placed in a 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: Dipole is the combination of two equal but opposite charges, kept at a certain distance. If it is placed in a uniform electric field, both the charges will suffer the same but opposite forces on them. As a result, the net force on the dipole becomes zero, but due to equal and opposite forces acting on two different points, there is a net torque acting on the dipole.
