Question

A uniform rod of length 'l' and mass 'm' is hung from two strings of equal length from a ceiling as shown in figure. The tensions in the strings are

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

From figure,
$T_A+T_B=mg.......\left(i\right)[\sum F_y=0]$
And $T_A\left(\frac{1}{2}\right)=T_B\left(\frac{1}{4}\right).......\left(ii\right)[\sum \tau =0]$
Solving (i) and (ii)
$T_A=\frac{mg}{3};T_B=\frac{2mg}{3}$
