Question

The water of volume 4 m³ at the height 20 m is pressed by 2 X 10⁵ N pressure. The work done by motor is

Moderate

A

8 x 10⁵ J
B

16 x 10⁵ J
C

12 x 10⁵ J
D

32 x 10⁵ J

Solution

Work done, $W = m g h + Δ p V = V ρ g h + Δ p V$
$= 4 \times 10^{3} \times 10 \times 20 + (2 \times 10^{5}) \times 4 = 16 \times 10^{5} J$
