If a stone tied at one end of a string is whirled and the string breaks, Why does the stone fly tangentially ?

A stone tied to a rope when whirled in hand, what force puts the hand ?

Breaking tension of string of length 1m is 40N. A body of mass 100g, is tied to the one end of the string and revolved in horizontal circle with another end fixed. Find maximum Angular velocity

A string of length L fixed at one end carries a mass M at the other end. The string makes 2/pi revolutions per second around the vertical axis through the fixed end as shown in the figure what is the tension in the string ?

A half kg weight is tied to one end of a metal wire of length 0.6 m . By holding the other end in the hand, the wire is whirled in a vertical and has an angular velocity of 2 r.p.s. at bottom of the circle. What is the elongation of the wire at the lowest point ? Area of cross-section of the wire = 5 x 10 ^(-6) m^2 . Y for steel = 2 x 10^10 N/m^2 .

A body at the end of a string moves in a vertical circle. The string always pulls the body towards the centre of the circle. Find the tension in the string when the body is at the highest point and at the lowest point.

Explain why there is a time lag between opening a scent bottle at one end of a room and smelling it at the other end, although molecular speeds are high?
