A body of mass m hangs at one end of a string of length l , the other end of which is fixed. It is given a horizontal velocity so that the string would just reach where it makes an angle of `60^(@)` with the vertical. The tension in the string at mean position is

A body of mass m hangs at one end of a string of length l, the other and of which is fixed . It is given a horizontal velocity so that the string would just reach where it makes an angle of 30^@ with the vertical . The tension in the string at mean position is

A body of mass m hangs at one end of a string of lenth l, the other end of which is fixed. It is given a horizontal velocity so that the string would just reach where it makes an angle of 60^(@) with the vertical. The tension in the string at bottommost point position is

A body of mass m hangs at one end of a string of lenth l, the other end of which is fixed. It is given a horizontal velocity so that the string would just reach where it makes an angle of 60^(@) with the vertical. The tension in the string at bottommost point position is

A body of mass m hangs at one end of a string of length Z, the other end of which is fixed. It is given a horizontal velocity so that the string would just become slack, when it makes an angle of 60^@ with the upward drawn vertical. The tension in string at this at this position is A. 4.5mg B. 2 mg C. 3 mg D. sqrt(mg)

A body of mass 40 kg is tied at one end of a string of length l. The body is oscillating in a vertical plane with angular amplitude theta_0 . What is the tension in the string when it makes and angle theta with the vertical ? If the breaking load for the string is 80 kgf, what can be the maximum angular amplitude of the body ?
