How many cities/towns are proposed to be supported for development as 'solar cities' during the 11th Five Year Plan period?
Which among the following represents the Lens formula?
\( \frac{1}{h} \) + \( \frac{1}{v} \) = \( \frac{1}{f} \)
\( \frac{1}{v} \)- \( \frac{1}{u} \)= \( \frac{1}{f} \)
\( \frac{1}{v} \)+ \( \frac{1}{f} \) = \( \frac{1}{u} \)
\( \frac{1}{v} \)+ \( \frac{1}{u} \) = \( \frac{1}{f} \)
