Prove that the tension throughout the string is uniform when the mass of string is considered to be zero.

One end of a string of length L is tied to the celling of lift accelerating upwards with an accelerating 2g The other end of the string is free. The linear mass density of the string varies linearly from 0 of lamda from bottom to top :-

A bird with mass m parches at the middle of a strectched string Show that the tension in the string is give by T=(mg)/(2sintheta). Assuming that each half of the string is straight.

Two sitar strings A and B playing the note 'Dha' are slightly out of tune and produce beats of frequency 5 Hz. The tension of the string B is slightly increased and the beat frequency is found to decrease to 3 Hz. What is the original frequency of B if the frequency of A is 427 Hz ?

Newton's laws of motion can be applied to a block in liquid also force due to liquid (e.g. upthrust) are also considered in addition to toher forces. A small block of weight W is kept inside. The block is attached with a string connected to the bottom of the vessel. Tension in the string is W//2 Q. The string is cut. find the time when it reaches the surface of the liquid

In the following figure, if the tension in the string AB is 51N, then the tension in the string BC will be :- ltimg src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/ALN_PHY_R03_E05_005_Q01.png" width="80%"gt

A bob of mass 0.1 kg hung from the ceiling of a room by a string 2 m long is set into oscillation. The speed of the bob at its mean position is 1 m s^(-1) . What is the trajectory of the bob if the string is cut when the bob is (a) at one of its extreme positions, (b) at its mean position.

A string of mass per unit length mu is clamped at both ends such that one end of the string is at x = 0 and the other is at x =l . When string vibrates in fundamental mode, amplitude of the midpoint O of the string is a, tension in a, tension in the string is T and amplitude of vibration is A. Find the total oscillation energy stored in the string.

A ball of mass m is attached to a string whose other end is fixed. The system is free to rotate in vertical plane. When the ball swings, no work is done on the ball by the tension in the string. Which of the following statement is the correct explanation?

A stone of mass 0.25 kg tied to the end of a string is whirled round in a circle of radius 1.5 m with a speed of 40 rev./min in a horizontal plane. What is the tension in the string ? What is the maximum speed with which the stone can be whirled around if the string can withstand a maximum tension of 200 N ?
