If a man at the equator would weight (3/...

If a man at the equator would weight (3/5)th of his weight, the angular speed of the earth is:

A

40 atm

B

52 atm

C

32 atm

D

62 atm

Text Solution

Verified by Experts

The correct Answer is:
B
Absolute pressure `p=p_(a)+ rho gh`
here `p_(a)=1.01xx10^(5) Pa`
`rho=1.03xx10^(3) kgm^(-3)`
`therefore " " p=1.01xx10^(5) Pa+ 51.5xx10^(5) Pa`
`=1.01xx10^(5) Pa + 51.5xx10^(5) Pa`
`=52.5xx10^(5) Pa=52 atm`
