The total charge enclosed for the inner sphere is 'q'.
 
Hence, the surface charge density for the inner sphere is
sigma inner = q /4piR1^2
 
The total charge enclosed for the outer sphere is 'Q+q'.
 
Hence, the surface charge density for the outer sphere is 
sigma inner = q /4piR1^2
 
The electric field at a point at a distance x from the sphere is given by Gauss' law 
 
by imagining a sphere of radius x.
