A particle with mass m is at rest on top of a smooth massive infinitely long cylinder lying on a horizontal plane. The radius of the cylinder is r . A small push is applied to the particle to get it sliding down the cylindrical surface. The particle leaves the surface at a point B on the cylinder which is at a height h and reaches the ground at a distance x from the cylinder. A cross-sectional view is shown in the fi
Options
- Ah is independent of m and depends on r .
- Bx is independent of m and r .
- Cthe speed of the particle at point B is independent of m and depends on r .
- Dthe angle is greater than 45^ .
