Light passes successively through two polarimeters tubes each of length $$0.29m$$. The first tube contains dextro rotatory solution of concentration $$60kgm$$–$$3$$ and specific rotation $$0.01rad$$ $$m2kg$$–$$1$$. The second tube contains laevo rotatory solution of concentration $$30kg/m3$$ and specific rotation $$0.02$$ $$radm2kg$$–$$1$$. The net rotation produced is
