A string breaks if its tension exceeds 10 newtons. A
\( \mathrm{P} \)
stone of mass \( 250 \mathrm{gm} \) tied to this string of length 10
W
\( \mathrm{cm} \) is rotated in a horizontal circle. The maximum angular velocity of rotation can be.
(1) \( 20 \mathrm{rad} / \mathrm{s} \)
(2) \( 40 \mathrm{rad} / \mathrm{s} \)
(3) \( 100 \mathrm{rad} / \mathrm{s} \)
(4) \( 200 \mathrm{rad} / \mathrm{s} \)
