Question

A hollow cylinder of mass m is suspended through two strings wrapped around it as shown in figure. Find the tension T in each string.

• A. $\frac{mg}{4}$
• B. $\frac{mg}{6}$
• C. $\frac{2mg}{3}$
• D. $\frac{mg}{2}$

Answer 1

The correct option is D $\frac{mg}{2}$

$\begin{array}{c}\text{From diagram,}\\ \text{as two strings symmetrically}\\ \text{bearing the weight of cyllinder}\\ \text{hence,}\\ \begin{array}{c}2T=mg\\ \text{on}T=\frac{mg}{2},T=\text{Tension in the String}\end{array}\end{array}$

Ans D
