(A) : Wooden block floats in a liquid and some fraction of its volume is immersed in the liquid. If the vessel is accelerated upwards with some acceleration then the fraction of volume immersed remains constant. (R ) : The block experience a net upward force which can be provided by extra up thrust. So the volume immersed will increase.
