Question

The diagram shows a
simple mercury barometer.
The mercury level is at a
height h when the atmospherich Paz
pressure is 100000 Pa.
0.4 h.
What is the pressure at P?
(A) 40000 Pa
(B) 60000 Pa
(C) 100000 Pa
(D) 140000 Pa

Answer 1

Answer:

The common error is to think that pressure at 0.4h above the surface of the reservoir of mercury is 0.4 times the atmospheric pressure. The pressure at p is caused by the weight of mercury above point P. Thus preesure at P is equal to : 0.6x 100000 = 60000 Pa
