Question

A body B is capable of remaining stationary inside a liquid at the position shown in Fig. a. If the whole system is gently placed on smooth inclined plane (Fig. b) and is allowed to slide down, then $(0<\theta <{90}^o)$

• 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 C the body will remain stationary (relative to liquid)

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