JEE Main2019Physics
Q.
A particle of mass 20 g is released with an initial velocity 5 m/s along the curve from the point A, as shown in the figure. The point A is a height h from point B. The particle slides along the frictionless surface. When the particle reaches point B, its angular momentum about O will be: (Take g = 10 m/s2)
- A
2 kg-m2/s
- B
3 kg-m2/s
- C
8 kg-m2/s
- D
6 kg-m2/s
