The spring balance $A$ reads $2 \mathrm{kg}$ with a block suspended from it. Another balance $B$ reads $5 \mathrm{kg}$ when a beaker with liquid is put on the pan of the balance. The two balances are now so arranged that the hanging mass is inside the liquid in the beaker as shown in figure. In this situation

Streamline flow is more likely for liquids with

The area of two holes $A$and $B$are $2a$and $a$respectively. The holes are at height $\left(\frac{H}{3}\right)$ and $\left(\frac{2H}{3}\right)$ from the surface of the water. Find the correct option(s):

A cylindrical vessel of$90 \mathrm{cm}$height is kept filled up to the brim as shown in the figure. It has four holes $1, 2, 3, 4$which are respectively at heights of $20 \mathrm{cm}, 30 \mathrm{cm}, 40 \mathrm{cm}$ and $50 \mathrm{cm}$ from the horizontal floor $PQ.$ The water falling at the maximum horizontal distance from the vessel comes from
