Question

Due to the dipole shown in figure, the electric intensity will be parallel to the dipole axis at the point :

• A. Q
• B. P
• C. both P and Q
• D. neither P nor Q

Hint:

Use symmetry to resolve electric field components in dipole problems.

Answer 1

The Correct Option is C

Concept: Electric field of dipole:
• On axial line → along dipole axis
• On equatorial line → opposite to dipole axis

Step 1: Point P.
P lies on axial line $\Rightarrow$ field along axis.

Step 2: Point Q.
At symmetric point, perpendicular components cancel, leaving resultant along axis.

Step 3: Conclusion.
\[ \text{Field is along dipole axis at both points} \]
