NEET Circular Motion PYQ practice sheet

4 previous-year NEET Physics questions from Circular Motion, newest papers first. Circular Motion carries 5 of the Physics questions in NEET 2020 to 2026, so this is a good place to test yourself after revising the chapter. Marking: +4 correct, −1 wrong.

   A frictionless circular wire of unit radius is fixed on the horizontal plane. Two-point particles of unit mass start moving simultaneously from point $A\left(\theta = \frac{\pi}{2}\right)$ with identical uniform angular speeds in opposite directions, and meet again at point $B\left(\theta = -\frac{\pi}{2}\right)$. During this time, which of the following figures schematically represent the magnitude of the total linear momentum $P$ of the system, as a function of $\theta$? Figure: a circular wire with $A$ at the top and $B$ at the bottom; the two particles start from $A$ and move in opposite directions along the circle, each reaching $B$. In the options, $\theta$ runs from $\pi/2$ (left end of the axis) to $-\pi/2$.

   A car travels on a circular racetrack of radius $50$ m, which is banked at an angle $\theta$. If the car travels at a speed $10\ \mathrm{ms^{-1}}$, then the wear and tear on its tyres is minimum. Taking the acceleration due to gravity to be $10\ \mathrm{ms^{-2}}$, the value of $\theta$ is:

   • (A)
     $\tan^{-1}\left(\frac{2}{5}\right)$
   • (B)
     $\tan^{-1}(2\sqrt{3})$
   • (C)
     $\tan^{-1}\left(\frac{1}{5}\right)$
   • (D)
     $\tan^{-1}(\sqrt{3}/2)$

   A particle moving with uniform speed in a circular path maintains:

   • (A)
     varying velocity and varying acceleration.
   • (B)
     constant acceleration.
   • (C)
     constant velocity.
   • (D)
     constant velocity but varying acceleration.

   A bob is whirled in a horizontal plane by means of a string with an initial speed of $\omega$ rpm. The tension in the string is $T$. If speed becomes $2\omega$ while keeping the same radius, the tension in the string becomes:

   • (A)
     $T$
   • (B)
     $\sqrt2\,T$
   • (C)
     $4T$
   • (D)
     $\dfrac{T}{4}$
