Question
Statement I : A cyclist is moving on an unbanked road with a speed of 7 kmh–1 and takes a sharp circular turn along a path of radius of 2m without reducing the speed. The static friction coefficient is 0.2. The cyclist will not slip and pass the curve $\left(\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^2\right)$
Statement II: If the road is banked at an angle of $45^{\circ}$, cyclist can cross the curve of 2 m radius with the speed of $18.5 \mathrm{kmh}^{-1}$ without slipping.
In the light of the above statements, choose the correct answer from the options given below.
Select the correct option:
A
Statement I is incorrect and statement II is correct
B
Statement I is correct and statement II is incorrect
C
Both statement I and statement II are false
