  • Option 1)

    E_e= 2E_a

  • Option 2)

    E _a= 2E_e

  • Option 3)

As we have learned

Electric Field and Potential due to an Electric Dipole -

At axial point

E_{axial}=\frac{2kpr}{\left ( r^{2}-l^{2} \right )^{2}}

V_{axial}=\frac{kP}{\left ( r^{2}-l^{2} \right )}

- wherein

 

     We have E_e=\frac{2Kp}{r^3}  and E_e=\frac{Kp}{r^3}; \therefore E_a= 2E_e 

 


Option 1)

E_e= 2E_a

Option 2)

E _a= 2E_e

Option 3)

E_a=E_e

Option 4)

  None of the above
