. A wire is replaced by another wire of same length and material but of twice diameter. (/) What will be the effect on the increase in its length under a given load? (//) What will be the effect on the maximum load which it can bear?

The length of a wire is reduced by half. What will be the effect on the increase in its length under a given load?

A wire stretches by a certain amount under a load. If the wire’s length and diameter are both doubled, the stretch caused by the same load is :

The following four wires are made of same material and same tensiom is applied to them . Which one will have maximum increase in length ?

When a certain weight is suspended to a long uniform wire its length increases by one cm. If the same weight is suspended to another wire of the same material and length but having a diameter half of the first one, the increase in its length will be

The following four wires are made of the same material. Which of these will have the largest extension when the same tension is applied ? L is the length and D is the diameter.

Specific resistance of the material of a wire is 44 x 10^6 Omega cm. If the resistance of the wire is 14 Omega and its diameter 1 mm, calculate the length of the wire.

A copper wire has diameter 0.5 mm and resistivity of 1.6 xx 10^-8Omega m. What will be the length of this wire to make its resistance 10Omega ? How much does the resistance change if the diameter is doubled?

A sonometer wire emits a note of frequency 150 Hz.What will be the frequency of the note emitted by it if its tension increaeed in the ratio 9:16 and the length is doubled?

A wire of given material having length I and area of cross-section A has a resistance of 8Omega . What would be the resistance of another wire of the same material having length l/2 and area of cross-section 4A?

Two wire made of same material and ratio of their length is 1:2 and ratio of raidus is 2:1. If they are strecthed by same force calculate the ratio of increase in length.
