Question

An electric dipole of moment p is placed at the origin along the x-axis. The electric field at a point p , whose position vector makes an angle $\theta$ with the x-axis, will make an angle ..... with the x-axis, where
$tan\alpha =\frac{1}{2}tan\theta$

• A. $\alpha$
  
• B. $\theta$
  
• C. $\theta +\alpha$
  
• D. $\theta +2\alpha$

Answer 1

The correct option is C $\theta +\alpha$


As given that $tan\alpha =\frac{1}{2}tan\theta$ So the angle made by the electric field vector with X- axis is $\theta +\alpha$.
