Section-C: Comprehension TypeFor Problems (1-3)
A particle of mass M attached to an inextensible string is moving in a vertical circle of radius R about fixed point O. It is imparted a velocity u in horizontal direction at lowest position as shown in figure.
Following information is being given:
(i) Velocity at a height h can be calculated by using formula v2 = u2 – 2gh.
(ii) Particle will complete the circle .
(iii) Particle will oscillates in lower half if .
(iv) The magnitude of tension at a height ‘h’ is calculated by using formula .
If M = 2 kg, R = 2m and u = 10 m/s the velocity of particle when θ = 60°,
