The escape velocity of a projectile on the earth's surface is \( 11.2 \mathrm{kms}^{-1} \). A body is projected out with thrice this speed. The speed of the body far away form the earth will be
[BHU 2006; Similar MP PMT 2013]
(a) \( 22.4 \mathrm{~km} \mathrm{~s}^{-1} \)
(b) \( 31.7 \mathrm{~km} \mathrm{~s}^{-1} \)
(c) \( 33.6 \mathrm{~km} \mathrm{~s}^{-1} \)
(d) None of these
