Answer 1

The position of the centre of mass of a uniform semi-circular wire of radius 'R' placed in x-y plane with its centre at the origin and the line joining its ends as x-axis is given by `(0, (xR)/pi)`. Then, the value of |x| is 2.

Explanation:

COM of ring is at centre of ring and of semi-circular ring is at `(2R)/pi`.

 

Hence, value of x = 2.
