A cubical vessel of height `1` m is full of water. What is the workdone in pumping water out of the vessel?

A

1250 J

B

5000 J

C

1000 J

D

2500 J

Text Solution

Verified by Experts

The correct Answer is:
B
Volume of water, `V=(1)^(3) m^(3) =1 m^(3)`
Density of water, `rho=10^(3)` kg `m^(-3)`
Mass of the water, `m=V rho = 10^(3) kg`.
Work done, `W= mgh = 10^(3) xx 10 xx (1)/(2) =5000` J.
