A shell of radius 1m is coated with a thin layer of B active material It s initial charge is zero and initial number of active atoms is x 10 2 If half life of 4 3 decay is 1 8 hr and all the electron are emitted with an energy of 1 44 keV find the time in hr after which charge on the sphere becomes constant Neglect the time taken by electron to return back
