A non-conducting ring of radius R having uniformly distributed charge Q starts rotating about x-x' axis passing through diameter with an angular acceleration `alpha`, as shown in the figure. Another small conducting ring having radius `a(altltR)` is kept fixed at the centre of bigger ring is such a way that axis xx' is passing through its centre and perpendicular to its plane. If the resistance of small ring is `r = 1Omega` , find the induced current in it in ampere.
(Given `q=(16xx10^(2))/(mu_(0))C, R=1m,a=0.1m,alpha="8rad s"^(-2)`
