if `3times10^(-3)J` of work is done in stretching wire through 1mm ,the workdone in stretching wire of same material having same dimensions it through 3mm is

If the work done in stretching a wire by 1mm is 2J , then work necessary for stretching another wire of same material but with double radius of cross -section and half of the length by 1 mm is

Where does the work done go during the stretching of a wire ?

A wire is stretched by one mm by a force of 1 kN. The work done is stretching the wire is

The work done in stretching an elastic wire per unit volume is or strain energy in a stretched string is

A spring 40 mm long is stretched by the application of a force. If 10 N force required to stretch the spring through 1mm, then the work done in stretching the spring through 40 mm is

Will current flow more easily through a thick wire or a thin wire of the same material when connected to the same source ? Why ?

Will current flow more easily through a thick wire or a thin wire of the same material when connected to the same source ? Why ?

(a) A wire 4 m long and 0.3mm in diameter is stretched by a force of 100 N. If extension in the wire is 0.3 mm, calculate the potential energy stored in the wire. (b) Find the work done is stretching a wire of cross-section 1mm^(2) and length 2 m through 0.1 mm. Young's modulus for the material of wire is 2.0xx10^(11) Nm^(-2) .

A 94.2 cm long sitar string of 1mm diameter is tuned by stretching it 1.0 cm. Calculate (i) the tension (ii) the work done in stretching the wire (Young's modulus of the material of the wire is 6 xx 10^(10) N//m^(2) ).

A Steel wire is 1m long and 1mm^(2) in area of cross-section. If it takes 200N to streach this wire by 1mm , the forces that will be required to stretch the wrie of the same material and cross-sectional area form a length of 10m to 1002cm
