NDA 2026 Physics question
A bicycle racing track is a level circular road of radius 10 m. Three cyclists P, Q and R with identical cycles are cycling on the track with speeds 2 m/s, 3 m/s and 5 m/s respectively. If the coefficient of friction between the tyres and the road is 0·1, then which cyclist will slip ? (Take )
Answer: (C)
Solution
On a level road friction provides the centripetal force, so the maximum safe speed is $ = = {0.1 ×
