A child revolves a stone of mass 0 .5 kg tied to the end of a string of length 40 cmin a vertical circle . The speed of the stone at the lowest point of the circle is `3 m//s` Calculate tension in the string at this point.

A stone is tied to the end of a string of length 1 and whirled in a horizental circle. When the string breaks then stone

IF a stone is tied to one end of the string and whirled in verticle circle, then the tension in the string at the lowest point is equal to

A stone of mass 0.2 kg is tied to one end of a string of length 80cm Holding the other end, the stone is wirled into a vertical circle. What is the minimum speed of the stone at the lowest point so that it just completes the circle What is the tension in the string at the lowest point of the circular path ? . (g =10^(-2)) .

A stone of mass of 1 kg is tied to the end of a string 1 m long. It is whirled in a vertical circle. The velocity of the stone at the bottom of the circle is just sufficient to take it to the top of circle without slackening of the string. What is the tension in the string at the top of the circle? (Take, g =10 ms^(-2) )

A stone is fastened to one end of a string and is whirled in a verticla circle of radius R. Find the minimum speed the stone can have at the highest point of the circle.

A stone of mass 0.2 kg is tied to one end of a string of length 80 cm. Holding the other and, the stone is whiled into a vertical circle. The minimum speed of the stone and tension at the lowest point of circular path so that it just comletes the circle are

A stone of mass 250 gram , attached at the end of a string of length 1.25 m is whirled in a horizontal circle at a speed of 5 m/s . What is the tension in the string ?

A stone of mass 100 g attached to a string of length 50 cm is whirled in a vertical circle by giving it a velocity of 7 m/s at the lowest point. Find the velocity at the highest point .

A body of mass 100 gram is tied at the end of a string of length 1m. It is rotated in a vertical circle at a critical speed of 4 m/s at the highest point . The tension in the string at the huighest point in its path is [ take g=10 m//s^(2) ]
