Question

Q. 23. The pressure on a
swimmer 10 m below the
2 points
surface of a lake is *
O (A) 1 atm
O (B) 2 atm
O (C) 3 atm
O (D) 4 atm​

Answer 1

Answer:

2 atm

Explanation:

let atmospheric pressure=p=1.05x10^5pa

pressure 10m below surface of lake

p=p+pgh

=1.05x10^5+1000x9.8x10

1.99X10^5pa

= 2 atm

Answer 2

Answer:

( B ) 2 atm

Explanation:

Let atmospheric pressure

= P = 1.05 × 10 ^ 5 pa

Pressure 10 m below surface of lack

P = p + pgh

= 1.05 × 10 ^ 5 + 1000 × 9.8 × 10

1.99 × 10 ^ 5 pa

= 2 Atm
