Question
A disc which several groves are cut along the chord drawn from a ‘A’, is arranged in a vertical plane, survival particles slipping from ‘A’ along the grooves simultaneously. Assuming friction and resistance negligible, the time take in reaching the edge of disc will be : -
Options
A.Maximum in groove AB
B.Maximum in groove AD
C.Same in all grove
D.According to the heights of B, C, D, E, F
Solution
Time to fall =
So it does not depend on i.e. the chord position.
