A wire of length `2m` is made from `10 cm^(2)` of copper. A force F is applied so that its length increases by `2mm`. Another wire of length `8m` is made from the same volume of copper. If the force F is applied to it, its length will increase by

Keeping one end of a wire of length L and radius r fixed, a force F is applied at the other end to elongate it by l. Another wire made of same material but of length 2L and radius 2r is stretched by a force 2F. Its increase in length will be

A wire of length L and radius r is clamped rigidly at one end. When the other end of the wire is pulled by a force f its length increases by l. Another wire of the same material of length 2L and radius 2r is pulled by a force 2f. Then find the increase in length of this wire.

A wire of length L and radius r is clalmped rigidly at one end. When the other end of the wire is pulled by force f, its length increaes by l. Another wire of the same material of length 2 L and radius 2 r, is pulled by a force 2 f. Find the increase in length of this wire.

When a load of 10 kg is suspended on a metallic wire, its length increase by 2 mm. The force constant of the wire is

When a load of 10 kg is suspended on a metallic wire, its length increase by 2 mm. The force constant of the wire is

A wire of length L and radius r is clamped at one end. If its other end is pulled by a force F, its length increases by l . If the radius of the wire and the applied force both are reduced to half of their original values keeping original length constant. Find the ratio of the change in length of first wire versus second wire?

When a stress of 10^(8) Nm ^(-2) is applied to a suspended wire its length increases by 1 mm. Calculate Young's modulus of wire.

A particular force (F) applied on a wire increases its length by 2 xx 10^(-3) m. To increases the wire's length by 4 xx 10^(-3) m, the applied force will be
