Question

A particle of mass 'm' is moving along a circle of radius 'r'. At some instant, its speed is 'v' and it is gaining speed at a uniform rate'a', then, at the given instant, acceleration of the mparticle is :

Answer 1

Explanation:

If T1, T2, T3 are the tensions in the strings in the three cases, we have 29 T = 2mimag mi + m2 2 x 2 x 29 2+2 T = 2 x 3 x 2g 3+2 = 2.49 T. – 2x1x 29 = 1.33 g 13 = 1+2 As x « T and

T2>T1>T3

∴x2>x1>x3
