A tube `1 cm^2` in cross- section is attached to the top of a vessel 1 cm high and of cross - section 100 `cm^2` Water is poured into the system filling it to a depth of 100 cm above the bottom of the vessel as shown in fig. Take g =10 `ms^(-2)` .

Options

A. The force exerted by water against the bottom of the vessel is `100 N`.
B. The weight of water in the system is `1.99 N`.
C. Both (a) and (b) are correct
D. Neither (a) nor (b) is correct

Answer

C

Explanation

`P=100cmxx1gcm^(-3)xx1000cms^(-2)=10^(5)dyncm^(-2)`
`F=10^(5)xx100dyn=100N`
Again `V=199cm^(3)`
Weight `= 199xx1xx1000dyn=1.99N`
