Question
When a weight $w$ is hung from one end of the wire other end being fixed, the elongation produced in it be $l$. If this wire goes over a pulley and two weights w each are hung at the two ends, the elongation of the wire will be(a) $4 l$(b) $2 l$(c) $\vec{l}$(d) $1 / 2$
Step 1
Step 1: The Young's modulus (Y) is given by the formula: \[Y = \frac{F}{A} \cdot \frac{L}{\Delta L}\] where F is the force applied, A is the cross-sectional area, L is the original length, and $\Delta L$ is the change in length. Show more…
