Question 3. A cyclist goes round a circular path of circumference 343 m in s. The angle made by him, with the vertical is (a) 440 (b) 420 (c) 430 (d) 450 Answer
Correct option is A) Velocity of cyclist is v= 22 34.3 and radius of the circular path is r= 2π 34.3 For circular motion, tanθ= rg v 2 = 2π 34.3 ×9.8 ( 22 34.3 ) 2 =1 or θ=45 o .
