उत्तर

Given:

v = 25 m/s,

r = 200 m,

g = 9.8 m/s2

To find:

Angle of banking (θ) = ?

Formula:

`tan theta = (v_max^2)/(rg)`

∴ `tan theta = ((25^2))/(200 xx 9.8)`

∴ `tan theta = 625/1960`

∴ `tan theta = 0.3189`

∴ θ = tan−1 (0.3189)

∴ θ = 17°41'

Therefore, the angle of banking of the track should be approximately 17°41' to allow a car to be driven safely along it at a maximum speed of 25 m/s.
