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 child revolves a stone of mass 0.5 kg tied to the end of a string of length 40 cm in a vertical circle. The speed of the stone at the lowest point of the circle is 2 m/s calculate the tension in the string at this point.

A stone of mass 2 kg is tied to one end of a string of length 0.5 m. It is whirled in a vertical circle. If the velocity of stone at the top is circle is 5 ms^(-1) , the tension in the string at the bottom of circle is

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

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 of mass of 1 kg is tied to the end of a string 1 m long. It is whirled in a vertical circle.
