Question:

Figure shows electric field lines in which an electric dipole \(\vec{p}\) is placed as shown. Which of the following statement is correct?

Options:

The dipole will not experience any force

The dipole will experience a force in the direction of \(\vec{p}\)

The dipole will experience a force opposite to \(\vec{p}\)

The dipole will experience a force perpendicular to \(\vec{p}\)

Correct Answer:

The dipole will experience a force opposite to \(\vec{p}\)

Explanation:

$\text{Field line density is decreasing along dipole moment }$

$\text{ Electric field is higher at -q and lower at +q}$

$ \text{ Electric force is more at -q that at +q}$

$\Rightarrow \text{Net force will be opposite to dipole moment}$
