A soap bubble of radius `r` is formed inside another soap bubble of radius `R (gt r)`. The atmospheric pressure is `P_(0)` and surface tension of the soap solution is T. Calculate change in radius of the smaller bubble if the outer bubble bursts. Assume that the axcees pressure inside a bubble is small compared to `P_(0)`.
