NEET · Physics · STD 12 - 2. Electric potential and capacitance
A short electric dipole has a dipole moment of \(16 \times 10^{-9}\, Cm .\) The electric potential due to the dipole at a point at a distance of \(0.6\, m\) from the centre of the dipole, situated on a line making an angle of \(60^{\circ}\) with the dipole axis is \(.........V\) \(\left(\frac{1}{4 \pi \epsilon_{0}}=9 \times 10^{9} Nm ^{2} / C ^{2}\right)\)
- A zero
- B \(50\)
- C \(200\)
- D \(400\)
Answer & Solution
Correct Answer
(C) \(200\)
Step-by-step Solution
Detailed explanation
\(V=\frac{k P \cos \theta}{r^{2}}=\frac{9 \times 10^{9} \times 16 \times 10^{-9}}{(0.6)^{2}} \times \frac{1}{2}\) \(V=200\, V\)
