A particle is thrown vertically upward. Its velocity at half of the height is \( 10 \mathrm{~m} / \mathrm{s} \), then the maximum
\( \mathrm{P} \) height attained by it \( \left(g=10 \mathrm{~m} / \mathrm{s}^{2}\right) \)

W
(a) \( 8 \mathrm{~m} \)
(b) \( 20 \mathrm{~m} \)
(c) \( 10 \mathrm{~m} \)
(d) \( 16 \mathrm{~m} .(2001) \)
