Physics Question on Electric charges and fields
An electric dipole placed in a nonuniform electric field experiences
A
both a torque and a net force
B
only a force but no torque
C
only a torque but no net force
D
no torque and no net force
Answer
both a torque and a net force
Explanation
Solution
If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.
