Two inclined frictionless tracks of different inclinations meet at A from where two blocks P and Q of different masses are allowed to slide down from rest at the same time, on each track, as shown in the figure. Then \(\left[\text { given }: \theta_{2}>\theta_{1}\right]\)
- both blocks will reach the bottom at the same time
- block Q will reach the bottom earlier than block P
- both blocks will reach the bottom with the same speed
- block Q will reach the bottom with a higher speed than block P.
Answer
(B) block Q will reach the bottom earlier than block P, (C) both blocks will reach the bottom with the same speed
