A cylindrical container contains water. A cubical block is floating in water with its lower surface connected to a spring.
(a) Suppose that the spring is in relaxed state. Now, if the whole contaienr is accelerated vertically upwards. Will the spring get compressed?
(b) Suppose that the spring is initially compressed. Now, what will happen to the state of the spring when the container is accelerated upwards?
(c) Assume that mass of the block is 1 kg and initially the spring (force constant k=100 N/m) is compressed by 5cm. when the container is accelerated up by an acceleration of `5m//s^(2)`, the spring has a total compression of 6cm. Calculate the chnag ein volume of block submerged inside water when the container gets accelerated. Density of water is `10^(3) kg//m^(3)`.

Answer

(a) No
(b) spring will get compressed more
(c) `100cm^(3)`
