Question

A body $B$ is capable of remaining stationary inside a liquid at the position shown in Fig.4.205 (a). If the whole system in gently placed on smooth inclined plane (Fig.4205 (b)) and is allowed to side down, then $(O<\theta <{90}^o)$

• A. The body will move up (relative to liquid)
• B. The body will move down (relative to liquid)
• C. The body will remain stationary (relative to liquid)
• D. The body will move up for some inclination $\theta$ and will move down for another inclination $\theta$

Answer 1

The correct option is D The body will move up for some inclination $\theta$ and will move down for another inclination $\theta$

Due to acceleration down the plane ,both body B and liquid will received the same component of acceleration down the plane .
