Correct Answer: 16
Solution and Explanation
\(\frac{\tau_1}{\tau_2}\)=\(\frac{μ_1B_1sin 90}{μ_2B_2sin90 v}\)=\(\frac{1.2×10^{−30}×5×10^4}{2.4×10^{−30}×15×10^4}\)=\(\frac{1}{6}\)

Concepts Used:
Electric Dipole
An electric dipole is a pair of equal and opposite point charges -q and q, separated by a distance of 2a. The direction from q to -q is said to be the direction in space.
p=q×2a
where,
p denotes the electric dipole moment, pointing from the negative charge to the positive charge.
