MCQ
Variation of atmospheric pressure, with height from earth is ................
- ALinear
- BParabolic
- ✓Exponential
- DHyperbolic
✓
Answer
Correct option: C.
Exponential
c
(c)
(c)
Variation of atmospheric pressure due to height is given by the barometric formula
$P_h=P_0 e ^{-m g h / R T}$
Hence the decrease will be exponential.
