QAIPM-2012-Ph-1671: NEET 2012 Physics - Class 11 AIPM-2012-Ph-1671 Solution: A car of mass m is moving on a level circular track of radius…

A car of mass m is moving on a level circular track of radius R. If μs\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 μsmRg\sqrt{\mu_s mRg} μsRg\sqrt{\mu_s Rg} mRg/μs\sqrt{mRg/\mu_s} Rg/μs\sqrt{Rg/\mu_s}

Multiple Choice Options

  • A μsmRg\sqrt {{\mu _s}mRg} _ s _ m R g _
  • B Rgμs\sqrt {{{Rg} \over {{\mu _s}}}} _ s _ R g _ _
  • C mRgμs\sqrt {{{mRg} \over {{\mu _s}}}} _ s _ m R g _ _
  • D μsRg\sqrt {{\mu _s}Rg} _ s _ R g _

Step-by-Step Verified Solution

For smooth driving maximum speed of car v then m v 2 R = _ s m g v = _ s R g
