Two copper vessels $A$ and $B$ have the same base area but of different shapes. $A$ takes twice the volume of water as that $B$ requires to fill upto a particular common height. Then the correct statement among the following is
- ✓Pressure on the base area of vessels $A$ and $B$ is same.
- BPressure on the base area of vessels $A$ and $B$ is not same.
- CBoth vessels $A$ and $B$ weigh the same.
- DVessel $B$ weighs twice that of $A$.
Answer: A.
