A cyclist is moving in a circular track of radius $80 m$ with a velocity of $36 km h^{- 1}$ . He has to lean from the vertical approximately through an angle (Take $g = 10 m s^{- 2}$ )

Options:

Answer:

Solution:

$Here, r = 80 m, v = 36 kmh^{- 1} = 36 \times (5/18) ms^{- 1} = 10 m s^{- 1}$ $∴ tan θ = \frac{v ^{2}}{r g} = \frac{( 10 ) ^{2}}{80 \times 10} = \frac{1}{8}$ or $θ = tan^{- 1} (\frac{1}{8})$
