A car is traveling in uniform circular motion on a section of flat roadway whose radius is . The road is slippery, and the car i
s just on the verge of sliding off the roadway. If the car’s speed were now doubled, what would be the smallest radius of the curve it could drive on without slipping?
From Boyle's law, the volume of a fixed mass of a gas is inversely proportional to its pressure at constant absolute temperature. Therefore; P1V1 =P2V2; where PV is a constant hence; 12 × 6 = 3× p2 p2 = 72/3 = 24 atm Therefore; the new pressure will be 24 atm
