268672 A body of mass \(2 \mathrm{~kg}\) attached at one end of light string is rotated along a vertical circle of radius \(2 \mathrm{~m}\). If the string can withstand a maximum tension of \(140.6 \mathrm{~N}\), the maximum speed with which the stone can be rotated is

1 \(22 \mathrm{~m} / \mathrm{s}\)
2 \(44 \mathrm{~m} / \mathrm{s}\)
3 \(33 \mathrm{~m} / \mathrm{s}\)
4 \(11 \mathrm{~m} / \mathrm{s}\)

268673 A pilot of mass \(m\) can bear a maximum apparent weight 7 times of mg. The aeroplane is moving in a vertical circle. If the velocity of aeroplane is \(210 \mathrm{~m} / \mathrm{s}\) while diving up from the lowest point of vertical circle, then the minimum radius of vertical circle should be

1 \(375 \mathrm{~m}\)
2 \(420 \mathrm{~m}\)
3 \(750 \mathrm{~m}\)
4 \(840 \mathrm{~m}\)

268674 The length of a ballistic pendulum is \(1 \mathrm{~m}\) and mass of its block is \(0.98 \mathrm{~kg}\). A bullet of mass 20 gram strikes the block along horizontal direction and gets embedded in the block. If block + bullet completes vertical circle of radius \(1 \mathrm{~m}\), then the striking velocity of bullet is

1 \(280 \mathrm{~m} / \mathrm{s}\)
2 \(350 \mathrm{~m} / \mathrm{s}\)
3 \(420 \mathrm{~m} / \mathrm{s}\)
4 \(490 \mathrm{~m} / \mathrm{s}\)
