Normal atmospheric pressure at sea-level is 105Nm-2 and the acceleration due to gravity is approximately 10ms-1. If the atmosphere has a uniform density of 1kgm-3, its height is
-
A.
100m -
B.
1000m -
C.
10 000m -
D.
100 000m -
E.
1000 000m
Correct Answer: Option C
Explanation
pressure = h x g x e
105 = 10 x h x 1
h = 104
