✓
Answer
(b)Time period in vibration magnetometer
$T = 2\pi \sqrt {\frac{I}{{M{B_H}}}} $, At poles ${B_H} = 0\;so\;T = \infty $
$T = 2\pi \sqrt {\frac{I}{{M{B_H}}}} $, At poles ${B_H} = 0\;so\;T = \infty $

A rigid uniform bar $A B$ of length $L$ is slipping from its vertical position on a frictionless floor (as shown in the figure). At some instant of time, the angle made by the bar with the vortical is $\theta$. Which of the following statements about its motion is/are correct?
→(image)
$[A]$ The midpoint of the bar will fall vertically downward
$[B]$ The trajectory of the point $\mathrm{A}$ is a parabola
$[C]$ Instantaneous torque about the point in contact with the floor is proportional to $\sin \theta$
$[D]$ When the bar makes an angle $\theta$ with the vertical, the displacement of its midpoint from the initial position is proportional to $(1-\cos \theta)$
