Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Least count $=\frac{1}{100}=0.01 \,mm$
Diameter of the wire
$=C S R \times L C $
$=52 \times 0.01 \,mm $
$=0.52 \,mm $
$d=0.052\, cm$

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
