Question
A ball whose size is slightly smaller than width of the tube of radius 2.5 m is projected from bottommost point of a smooth tube fixed in a vertical plane with velocity of 10 m/s. If N1 and N2 are the normal reactions exerted by inner side and outer side of the tube on the ball
- N1> 0 for motion in ABC, N2 > 0 for motion in CDA
- N1> 0 for motion in CDA, N2 > 0 for motion in ABC
- N2> 0 for motion in ABC & part of CDA
- N1 is always zero.
The correct answer is: N2> 0 for motion in ABC & part of CDA
