MCQ
Imagine the situation in which the given arrangement is placed inside a trolley that can move only in the horizontal direction, as shown in figure. If the trolley is accelerated horizontally along the positive $x$ -axis with $a_0$, then If $a_{min}$ and $a_{max}$ are the minimum and maximum values of $a_0$ for which the blocks remain stationary with respect to the surface, then identify the correct statements
- AIf $a_0 < a_{min}$, the block $m$ accelerates downward
- BIf $a_0 > a_{max}$, the block $m$ accelerates upward
- CThe block $m$ does not accelerate up or down when $a_{min} \leq a_0 \leq a_{max}$
- ✓All of the above
