A simple pendulum is suspended from the ceiling of a car taking a turn of radius 10 m at a speed of 36 km/h. Find the angle made by the string of the pendulum with the vertical if this angle does not change during the turn. Take `g=10 m/s^2`.

Answer

3

Explanation

`V = 10 m//s`
`tantheta = (v^(2))/(Rg)`
`rArr theta = tan^(-1) ((10 xx 10)/(10 xx 10)) = 45^(@)`
