A) both \[l\] and h increase
B) both \[l\] and h decrease
C) \[l\] decreases and h increases
D) \[l\] increases and h decreases
Correct Answer: B
Solution :
\[l\]will decrease because the block moves up. H will decrease because the coin will displace thevolume \[({{v}_{1}})\] of water equal to its own volumewhen it is in water whereas when it is on theblock it will displace the volume of water \[({{v}_{1}})\]whose weight is equal to weight of coin andsince density of coin is greater than the density of water \[{{v}_{1}}<{{v}_{2}}.\]You need to login to perform this action.
