MCQ
Consider a ring rolling down a smooth inclined plane of vertical height $'h\ '$ and inclination $\theta$. Then the true statement in the following is?
  • Acceleration along the plane is $g \sin\theta$ and the potential energy at the topmost point is $\ce{mgh.}$
  • B
    Acceleration along the plane is $g$ and the potential energy at the top most point is $\ce{mgh.}$
  • C
    Acceleration along the plane is $g \sin\theta$ and the potential energy at the top most point as $\ce{mgh} \sin\theta$
  • D
    None of these.

Answer

Correct option: A.
Acceleration along the plane is $g \sin\theta$ and the potential energy at the topmost point is $\ce{mgh.}$
Acceleration along the plane is $g \sin\theta$ and the potential energy at the topmost point is $\ce{mgh.}$

In a cylindrical water tank, there are two small holes $A$ and $B$ on the wall at a depth of $h_1$ , from the surface of water and at a height of $h_2$ from the bottom of water tank. Surface of water is at height of $h_2$ from the bottom of water tank. Surface of water is at heigh $H$ from the bottom of water tank. Water coming out from both holes strikes the ground at the same point $S$. Find the ratio of $h_1$ and $h_2$
A small roller of diameter $20 cm$ has an axle of diameter $10 cm$ (see figure below on the left). It is on a horizontal floor and a meter scale is positioned horizontally on its axle with one edge of the scale on top of the axle (see figure on the right). The scale is now pushed slowly on the axle so that it moves without slipping on the axle, and the roller starts rolling without slipping. After the roller has moved $50 cm$, the position of the scale will look like (figures are schematic and not drawn to scale)-
