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
- A⁻¹(4)
- B⁻¹(1 / 8)
- C⁻¹(1 / 4)
- D⁻¹(2)
Correct answer
B. ⁻¹(1 / 8)
Step-by-step solution
array r Here, r=80 ~m , v=36 kmh ⁻¹=36 (5 / 18) ms ⁻¹ =10 ~m ~s ⁻¹ array = v^2 r g = (10)^2 80 10 = 1 8 or = ⁻¹ ( 1 8 )
