A man throws balls with the same speed vertically upwards one after the other at an interval of 2 seconds. What should
\( \mathrm{P} \) be the speed of the throw so that more than two balls are in

W the sky at any time (Given \( g=9.8 \mathrm{~m} / \mathrm{s}^{2} \) ) [CBSE PMT 2003]
(a) At least \( 0.8 \mathrm{~m} / \mathrm{s} \)
(b) Any speed less than \( 19.6 \mathrm{~m} / \mathrm{s} \)
(c) Only with speed \( 19.6 \mathrm{~m} / \mathrm{s} \)
(d) More than \( 19.6 \mathrm{~m} / \mathrm{s} \)
