A given element in a star is giving out radiations of certain wavelength. The wavelength, when sighted on earth has a shift of \( 0.032 \% \) towards the longer wavelength side. What is the velocity of the star in the line of sight ? Given, the velocity of light, \( c=3 \times 10^{8} \mathrm{~m} \mathrm{~s}^{-1} \).
