Light passes successively through two polarimeter tubes each of length 0.29 m. The first tube contains dextro-rotatory solution of concentration 60 kg m^-3 and specific rotation 0.01 rad m^2 kg^-1 . The second tube contains laevo-rotatory solution of concentration 30 kg m^-3 and specific rotation 0.02 rad m^2 kg^-1 . The net rotation produced is

theta is the optical rotation produced by sugar solution of concentration C and taken in a glass tube of length 0.2 m and radius r . Then the solution is transferred to another glass tube of length 0.3 m and radius r and the remaining space is filled with distilled water. The optical rotation produced by this solution is
