Question

Two short dipole of dipole moment p are placed at two corners of a square as shown in figure. What is the ratio of magnitudes of electric field intensity at two points O & A i.e. E_{at O} : E_{at A}?

• A. 2
• B. $2\sqrt{2}$
• C. 4
• D. $\sqrt{2}$

Answer 1

Answer: (B)

$2\sqrt{2}$

Answer 2

E_{at o} = 2

E_{at A} = $\sqrt { 2 }$

x² + x² = 4a² =

x² = 2a² = $\frac { 4 } { 1 }$x = $\sqrt { 2 }$a
