Questions
A disc and a sphere of same radius but different masses are rolling down two inclined planes of the same altitude and length.Which one of the two objects gets to the bottom of the plane first?
detailed solution
Correct option is B
Time to roll down the plane is given by T=2Laa = g sin θ1+K2R2For disc K2R2 = 12 = 0.5For sphere K2R2 = 25 = 0.4a(sphere) > a (disc)sphere reaches firstTalk to our academic expert!
