A car goes on a horizontal circular road of radius R = 
meter, the speed increasing at a constant rate 
= a = 1 m/s 2 , starting from rest. The friction coefficient between the road and the tyre is µ= 0.2 Find the time at which the car will skid.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(t = 3 sec)
Sol. Net force on car = frictional force f
∴ f = m 
(where m is mass of the car) ........
For skidding to just occur
f = µN = µmg ....
∴ From and
v = 
v = u + at ⇒ t = 
= 3 sec
