When a wire drawn until its radius decreases by `3%` then percentage of increase in resistance is-

If a copper wire is stretched to make its radius decrease by 0.1% , then the percentage increase in resistance is approximately -

If an iron wire is drawn to decrease its radius by0.5% .Then percentage of increase in its resistance will be

When length of wire is increased by 10% , then increase in resistance is

If a copper wire is stretched so that its length increases by 20% then what is the percentage increase in its resistance (assuming its volume remaing constant) ?

A wire has a resistance R. Find new resistance, (i) if radius of cross-section of a cylindrical wire is doubled, then find ratio of initial to final resistance. (ii) if length of wire is increased by 10% , then find the percentage increase in its resistance. (iii) if length of wire is increased by 20% , then find the percentage increase in its resistance.

A cylindrical wire is stretched to increase its length by 10%. The percentage increase in the resistance of the wire will be–

The radius of a circle is increased by 10 % . Find the percentage increase in its area.

If the radius of a circle is increased by 6 % , find the percentage increase in its area

A cylindrical wire is stretched to increase its length by 10%. Calculate the percentage increase in resistance.

If mass of body is increased by 20% and its speed is decreased by 20% then percentage decrease in magnitude of its momentum will be
