1.	A car of mass m is moving on a level circular track of radius R. If mu_s represents the static friction between the road and tyres of the car, the maximum speed of the car in circular motion is given by
Answer» `sqrt(mu_s Rg)` `sqrt((Rg)/(mu_s))` `sqrt((mRg)/(mu_s))` `sqrt((mu_sRg))` Solution :Forceof friction providesthenecessarycentripetal force . ` f lemu_s N =(mv^2)/(R ),v^2 LE(mu_sRN )/(m )` `v^2lemu_sRg"" [ :.N= MG ]` `ORV lesqrt( mu_sRg)` ` therefore` Themaximumspeedof thecar incircular MOTIONIS `v_("max") = sqrt( mu_sRg)`
