Positive charge is uniformly distrubuted...

Positive charge is uniformly distrubuted with volume charge density `rho` of sphere of radius R. A spherical cavity is created in the sphere as shown in figure. This electric field intensity inside the cavity at point P is(where CP =R/5 , `C_0 C` = 2R/3 , radius of cavity is R/4, `C_0` & C are centre of sphere & cavity respectively)
