The string in E sonometer is touched lightly at a point one-third of its length from one end. Which harmonics is produced ?

A string fixed at both ends is vibrating such that a point at quarter of its length from one end is a point of maximum displacement. The frequency of vibration in this mode is 100 Hz . If the frequency emitted when it vibrates in the next mode such that this point is again a point of maximum displacement is 100 k then find the value of k .

A string fixed at both is vibrating in the lowest mode of vibration for which a point at quarter of its length from one end is a point of maximum displacement . The frequency of vibration emitted when it vibrates in the next mode such that this point is again a point of maximum displacement ?

A string fixed at both ends is vibrating in the lowest mode of vibration for which a point at quarter of its length from one end is a point of maximum vibration . The note emitted has a frequency of 100 Hz . What will be the frequency emitted when it vibrates in the next mode such that this point is again a point of maximum vibratin ?

A string fixed at both ends, is vibrating in a particular mode of vibration. Vibration is such that a point on string is at maximum displacement and it is at a distance of one fourth of length of string from one end. The frequency of vibration in thus mode is 200 Hz . What will be the frequency of vibration when it vibrates in next mode such that the same point is at maximum displacement?

A uniform metal chain is placed on a rough table such that the one end of chain hangs down over the edge of the table, when one-third of its length hang over the edge, the chain starts sliding. Then the coefficient of static friction is

A uniform string resonates with a tuning fork, at a maximum tension of 32 N. If it is divided into two segments by placing a wedge at a distance one fourth of length from one end, then resonance frequency will occur at a maximum value of tension :-

One end of uniform wire of length L and of weight W is attached rigidly to a point in the roof and a weight W_(1) is suspended from its lower end. If s is the area of cross section of the wire, the stress in the wire at a height ( 3L//4 ) from its lower end is

One end of a wire of length L and weight w is attached rigidly to a point in roof and a weight w_(1) is suspended from its lower end. If A is the area of cross-section of the wire then the stress in the wire at a height (3L)/(4) from its lower end is

One end of a uniform wire of length L and of weight W is attached rigidly to a point in the roof and a weight W_(1) is suspended from its lower end. IF S is the area of cross-section of the wire, the stress in the wire at a height 3L/4 from its lower end is

A classroom is 45 feet long. Its breadth is one-third its length. Find the ratio of the breadth of the room to its perimeter.
