A small sphere of mass "M" suspended by a thread is first taken aside so that the thread forms the right angle with the vertical and then released. 1. The total acceleration of the sphere as a function of the angle with the vertical is :- a )g(1+cos^2 θ)^1/2 b) g(1+3cos^2 θ)^1/2 c) gcos θ d) gsin θ 2.The tension in the string as a function of angle θ with the vertical is :- c) mgcos θ d) mgsin θ b)mg(1+3cos^2 θ)^1/2 d)mg(1+cos^2 θ)^1/2 3. The tension in the string when the vertical component of the sphere's velocity is maximum is :_ a)mg b)mg/2^1/2 c)mg/3^1/2 d)mg/2


A small sphere of mass "M" suspended by a thread is first taken aside so that the thread forms the right angle with the vertical and then released.

1. The total acceleration of the sphere as a function of the angle  with the vertical is :-

a )g(1+cos^2θ)^1/2                     b) g(1+3cos^2θ)^1/2                        c) gcosθ                   d) gsinθ

2.The tension in the string as a function of angle θ with the vertical is :-

  c) mgcosθ                   d) mgsinθ                b)mg(1+3cos^2θ)^1/2           d)mg(1+cos^2θ)^1/2

3. The tension in the string when the vertical component of the sphere's velocity is maximum is :_

a)mg               b)mg/2^1/2              c)mg/3^1/2              d)mg/2
