An aeroplane of mass `3xx10^(4)kg` and total wing area of 120 `m^(2)` is in a level flight at some height the difference in pressure between the upper and lower surfaces of its wings in kilo pascal is `(g=10m//s^(2))`

A

`2.5`

B

`5.0`

C

`10.0`

D

`12.5`

Text Solution

Verified by Experts

The correct Answer is:
A
In level of flight of aeroplane, mg = PA
or `P=(mg)/(A)=(3xx10^(4)xx10)/(120)` pascals = `2.5` kPa
