A bucket water filled upto a height = 15...

A bucket 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 atmospheric pressure at the bottom is

A

`0.5kPa`

B

`1kPa`

C

`5kPa`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`P=hrhog_(eff)" "implies P=hrho(g-a)" "....(1)`
`a=((M-M//2)g)/(M+M//2)`
`a=(g)/(3)" "....(2)`
From (1) `&` (2)
`P=15xx10^(-2)xx10^(3)xx(g-g//3)" "impliesP=150xx(2g)/(3)`
`P=1000Pa" "=P=1kPa`

A bucket is in the form of a frustum of a cone and it can hold 28.49 litres of water. If the radii of its circular ends are 28 cm and 21 cm, find the height of the bucket.

A monkey of mass m climbs up to a rope hung over a fixed pulley. The opposite end of the rope is tied to a weight of mass M lying on a horizontal plane. Neglecting the friction, find the acceleration of both the bodies (relative to the plane) and the tension of the rope for the three cases: (i) The monkey does not move with respect to the rope (ii) The monkey moves upwards with respect to the rope with acceleration a. (iii) The monkey moves downwards with respect to the rope, with acceleration a.
