A stone tied at the end of a string is whirled in a circle. When the string breaks, the stone ___________ Correct Answer Flies away tangentially

The instantaneous velocity of the stone moving round the circle is along the tangent to the circular path. When the string breaks, the centripetal force vanishes. Due to the inertia of motion, the stone flies away tangentially.

There are two huts of two brothers each on the opposites sides of a medium sized pond. Each brother has to use 12 stones in the pond to visit each other’s hut by crossing the pond. These stones are numbered serially using numbers one to twelve. A dragon fly is jumping on these stones as follows; every minute it jumps to the fifth stone from where it started. Thus if it jumps from the fourth stone it would go to the ninth stone, from the ninth stone it would go to the second stone and so on. Select the option that indicates the number of stones on which this dragon fly would be resting if it stops jumping at the 36th minute if it starts jumping from the stone that is numbered two.
