A uniformly charged sphere is placed inside a charged hollow sphere as shown in the figure, `O` is the center of hollow sphere and `C` is the center of solid sphere. The magnitude of charge on both the spheres is `4(sqrt((3)/(7))) mu (C)`.The electric field at point `P` which lies just outside the hollow sphere is given by `3 alpha K`N/C. Find the value of `alpha`. (Here, `K=(1)/(4 pi varepsilon_(0)))`.
