A sitar wire is replaced by another wire of same length and material but of three times the earlier radius.If the tension in the wire remains the same,by what factor will the frequency change?

A cable is replaced by another of the same length and material but of twice diameter. How does this affect elongation under a given load?

A cable is replaced by another of the same length and material but of twice diameter. How many times will be the maximum load supported by the latter as compared to the former?

The radius of a wire is decreased to one third. If volume remains the same, the length will become

A wire of length I is cut into three pleces. What Is the probability that the three pieces form a triangle ?

A conductor of length L is connected across a dc source of e.m.f E. If the conductor is replaced by another of the same materials and area of cross-section but of length 5 L, by what factor will the drift velocity change?

Compare the resistance of two wires of same material. Their lengths are in the ratio 2:3 and their diameters are in the ratio 1:2

A uniform wire of resistance R is uniformly compressed along it s length, until its radius becomes n times the original radius. Now, the resistance of the wire becomes

Which has more resistivity, a thick or thin wire of the same material?

A wire of length L and 3 identical cells of negligible internal resistance are connected in series. Due to the current, the temperature of the wire is raised by DeltaT in a time t. A number N of similar cells is now connected in series with a wire of the same material and cross-section but of length 2L. The temperature of the wire is raised by the same amount DeltaT in the same time t. the value of N is
