A bucket contains water filled upto a height= 15 cm. The bucket is tied to a rope which is passed over a frictionless light pulley and the other end of the rope is tied to a weight of mass which is half of that of the (bucket+water). The water pressure above the atmospheric pressure at the bottom is

Options:

Answer:

Solution:

$P = h ρ g_{eff} \Rightarrow P = h ρ (g - a) ....(1)$

$a = \frac{(M - M / 2) g}{M + M / 2}$

$a = \frac{g}{3} ....(2)$

From (1) & (2)

$P = 15 \times 1 0^{- 2} \times 1 0^{3} \times (g - g / 3) \Rightarrow P = 150 \times \frac{2 g}{3}$

$P = 1000 P a \Rightarrow P = 1 kPa$
