A wire extends by

\mathrm{1 mm}

when a force is applied. Double the force is applied to another wire of same material and length but half the radius of cross-section. The elongation of the wire in mm will be

View answer and explanation

Correct option: A

\mathrm{8}

Option A (8) is correct because elongation is inversely proportional to the area and directly proportional to the force.
