Question

Professor PC Thomas Classes · Answer

$\mathrm{R}=2 \sqrt{\mathrm{~h}(\mathrm{H}-\mathrm{h})}$ R is maximum when $\mathrm{h}_{1}(\mathrm{H}-\mathrm{h})$ is maximum ie when $\mathrm{h}=\mathrm{H}-\mathrm{h}$\ or $\mathrm{h}=$\ Note:- when the sum of two quantities is a constant the product will be maximum when the quantities are equal\
