In a stretched wire under tension and fixed at both ends, the area of cross section of the wire is halved and the tension is doubled. The frequency of the wire will be

In a stretched string under tension and fixed at both ends, the tension is increased by four times, and the length is doubled, the frequency

The length of sonometer wire is doubled and the tension is increases four times. The frequency will

If the area of cross-section of a resistance wire is halved, then its resistance becomes:

A metallic wire of specific resistance s is stretched in such a way that its length is doubles and area of cross section is halved Then the specific resistance of the wire will be

Resistance of a wire of circular cross-section is 2 Omega . If both the length and radius of cross-section of the wire be halved, then what will be the resistance of the wire ?

A metal wire of length jl and area of cross - section A is fixed between rigid supports negligible tension . If this is cooled. The tension in the wire will be

A uniform wire under tension , is fixed at its ends. If the ratio of tension in the wire to the square of its length is 360 dyne /cm^2 and fundamental frequency of vibration of wire is 300Hz , find its linear density.

The tension in a sonometer wire is increased to nine times. Then the fundamental frequency of the wire is
