Question

A smooth ring of mass m can slides on a fixed horizontal rod. A string tied to the ring passes over a fixed pulley B and carries a block C of mass 2 m as shown below. As the ring starts sliding :

The acceleration of the ring is $\frac{2 g c o s q}{1 + 2 {c o s}^{2} q}$
The acceleration of the block is $\frac{2 g {c o s}^{2} q}{1 + 2 {c o s}^{2} q}$
The tension in the string is $\frac{2 m g}{1 + 2 {c o s}^{2} q}$
If the block descends with velocity $v$ then the ring slides with velocity $v c o s q$ .

The correct answer is: The acceleration of the block is $fraction numerator 2 g c o s to the power of 2 end exponent invisible function application q over denominator 1 plus 2 c o s to the power of 2 end exponent invisible function application q end fraction$
