\(Capillary\,rise,\,h = \frac{{2T\cos \theta }}{{r\rho g}}\)

\(For\,given\,value\,of\,T\,and\,r,h \propto \frac{{\cos \theta }}{\rho }\)

\(Also,{h_1} = {h_2} = {h_3}\,\,or\,\,\frac{{\cos {\theta _1}}}{{{\rho _1}}} = \frac{{\cos {\theta _2}}}{{{\rho _2}}} = \frac{{\cos {\theta _3}}}{{{\rho _3}}}\)

\(Since\,{\rho _1} > {\rho _2} > {\rho _{3'}}\,so\,\cos {\theta _1} > \cos {\theta _2} > \cos {\theta _3}\)

\(For\,0 \le \theta  < \frac{\pi }{2},{\theta _1} < {\theta _2} < {\theta _3}\)

\(Hence,\,0 \le {\theta _1} < {\theta _2} < {\theta _3} < \frac{\pi }{2}\)
