Electric field inside a solid sphere is linear function of radial distance and its value E at surface of sphere is given as
 
E = Q/ [ 4πεo R2 ]
 
Where Q is total charge content of sphere, R is radius and εo is permittivity of free space.
 
In the given graph, Electric field variation with respect to radial distance is linear upto 4 m,
hence radius of solid sphere is 4 m .
 
From the graph , we get electric field value at R = 4 m as  4 × tan37 = 3.
 
Hence we consider electric field at surface of sphere as 3 N/C
 
Hence E = Q/ [ 4πεo × 16 ] = 3 N/C  , hence  Q = 192 πεo  C
