A uniform round object of mass `M`, radius `R` and moment of inertia about its centre of mass `I_(cm)` has a light, thin string wrapped several times around its circumference. The free end of string is attaced to the celling and the object is released from rest. Find the acceleration of centre of the object and tension n the string. [ Take `(I_(cm))/(MR^(2))=k`]

Explanation

To solve this problem, we need to analyze the forces acting on the uniform round object and apply Newton's second law. Let's go through the solution step by step.

### Step 1: Identify the forces acting on the object
The forces acting on the object are:
- The weight of the object, \( W = Mg \), acting downward.
- The tension in the string, \( T \), acting upward.

### Step 2: Apply Newton's second law
