A body of mass `m` is rotated in a vertical circle of radius `R` by means of light string. If the velocity of body is `sqrt(gR)` while it is crossing highest point of vertical circle then the tension in the string at that instant is

If a bodyy is tied to a string and whirled in vertical circle, then the tension in the string at the highest position is

A body of mass m is rotated in a vertical circle with help of light string such that velocity of body at a point is equal to critical velocity at that point. If T_(1), T_(2) be the tensions in the string when the body is crossing the highest and the lowest positions then the following relation is correct

A point mass m is moved in vertical circle of radius r with help of string. Velocity of mass is root(7gr) at lowest point. Tension in string at lowest point is

A small stone of mass 50 g is rotated in a vertical circle of radius 40 cm. What is the minimum tension in the string at the lowest point?

A stone of mass 0.4 kg is tied to a string and rotated in a vertical circle of radius 1.2 m . Calculate the speed of the stone for which the tension in the string is zero at the highest point of the circle . What is the tension at the lowest point in this case ?

A body is mass m is rotating in a vertical circle of radius 'r' with critical speed. The difference in its K.E at the top and at the bottom is

A body is just being revolved in a vertical circle of radius R. The string breaks when the body is at the highest point . What is the horizontal distance covered by the body after the string breaks ?
