Two electric dipoles of moments \(p\) and \(27 p\) are placed in opposite direction on a line at a distance of \(24 \mathrm{~cm}\). The electric field will be zero at a point between the dipoles whose distance from the dipole of moment \(p\) is
- A \(6 \mathrm{~cm}\)
- B \(5 \mathrm{~cm}\)
- C \(10 \mathrm{~cm}\)
- D \(\frac{4}{13} \mathrm{~cm}\)
Answer & Solution
Correct Answer
(A) \(6 \mathrm{~cm}\)
Step-by-step Solution
Detailed explanation
Consider two dipoles are placed at two points \(A\) and \(B\) in opposite direction. Let \(P\) be the null point, where net electric field intensity is found to be zero. \(x\) be distance of point from electric dipole at \(A\). By using expression of electric field intensity at…
