If F is the breaking force of a wire, what will be the breaking force for (a) two parallel wires of the same size (b) for a single wire of double the thickness?

If the breaking force for a given wire is F, then the breaking force of two wires of same magnitude will be

A breaking force for a given wire is 'F'. The breaking force for the wire having double the thickness is

The breaking stress of a wire depends on

The breaking force for a wire of diameter D of a material is F. The breaking force for a wire of the same material of radius D is

Force between two parallel wires||Examples

If the thickness of the wire is doubled, then the breaking force in the above question will be

The breaking stress for a wire of unit cross-section is called

The breaking stress for a wire of radius r of given material is F N//m^(2) . The breaking stress for the wire of same material of radius 2r is:

If the current flowing in a copper wire be allowed to flow in another copper wire of same length but of doubled the radius, then what will be the effect on the drift velocity of the electrons. If the same current be allowed to flow in an iron wire of the same thickness, then ?

If the current flowing in a copper wire be allowed to flow in another copper wire of double the radius, then what will be the effect on the drift velocity of the electrons? If the same current be allowed to flow in an iron wire of the same thickness, then?
