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 body is tied to a string and whirled in vertical circle, then the tension in the string at the highest position 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 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 body of mass m is rotated along a verticle circle with the help of a light string such that velocity of the body at any point is critical. If T1 and T2 are tensions in the string when the body is crossing the highest and lowest points of the vertical circle respectively, then

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 ?
