Figure shows electric field lines in which an electric dipole p is placed as shown. Which of the following statements is correct?
A
The dipole will not experience any force.
B
The dipole will experience a force towards right.
C
The dipole will experience a force towards left.
D
The dipole will experience a force upwards.
Answer
The dipole will experience a force towards left.
Explanation
Solution
The spacing between electric lines of force increases from left to right. Therefore, E on left is greater than E on right. Force on +q charge of dipole is smaller and to the right. Force on −qcharge of dipole is bigger and to the left. Hence the dipole will experience a force towards the left.
