A pilot of mass 81 kg loops the loop with steady speed of `300 km//h`. If the radius is 0.5 km then the force with which the pilot is pressed into the seat at the highest point of the loop ,is `(g=10m//s^(2))`

A

`3.15xx10^(2) N`

B

zero

C

`8.10xx10^(2)N`

D

`19.35xx10^(2)N`

Text Solution

Verified by Experts

The correct Answer is:
A
`v=sqrt(gh)`
`=sqrt(9.8xx9.8xx10^(-1))`
`0.98 ms^(-1)`
