Question

at what depth below the surface of the sea level, water pressure becomes 5 times of the atmospheric pressure at sea level
(take gravity 10m/s²)

Answer 1

Answer:

Correct option is

A

21.2×10

5

N/m

2

The gauge pressure at any depth is given by,

P

g

=ρgh

Given, the atmospheric pressure to be P

o

=1.013×10

5

Pa

The pressure at this depth will be,

P=P

o

+P

g

= 1.013×10

5

+1.03×10

3

×10×200

= 21.2×10

5

Pa
