A barometer kept in an elevator accelerating downwards with acceleration Q . The most liekly pressure inside the elevator is ?

Text Solution

Verified by Experts

The resultant acceleration of elevator in downwards direction =g-a
`therefore` The pressure in elevator `=hrho(g-a)`
`=(76xx13.6xx(g-a))/(13.6xxg)`
This pressure is greater than the atmospheric pressure 76 cm Hg .
