if the particle starts from rest at point A and loses contact at point C then the relation b/w α and β is????
ans. :- 3sinβ=2cosα
Plz help how to do it...

Height of A from the ground is xcos(alpha).
From the right triangle consider cos(alpha) = Ha/x
And similarly sin(Beta) = Hb/x
Where x would be the radius of the sphere.
Hope that helps.
All the best,

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
