Question
a cyclist is moving in a circle of radius 20m with velocity 5ms-1mass =60kg of both boy & cycle find static friction on tyre
Joshi sir comment
v2/rg = µ
so µ = 5*5/20*10 = 1/8
Fs = µ * N = 1/8 * 60*10 = 600/8 = 75 N
µ is the coefficent of static friction, Fs is static friction and N is normal reaction
This answer is given by SHUBS and is correct answer
Read 2 Solution.
tanθ = v2/rg = µ
µ = 0.2
Fs = µ * N = 120N
N is normal reaction = 600N
Fs is static friction
µ is the coefficent of static friction

My apologies. I was in a hurry.
Fs = 75N
