Questions
A system of two identical rods (L-shaped) of m ass m and length I are resting on a peg P as shown in the figure. If the system is displaced in its plane by a small angle, find the period of oscillations.
detailed solution
Correct option is C
T=2πImgL Here I=ml23+ml23=2mgl23 From figure, sin45∘=Ll/2∴ L=l22∴ T=2π2ml23×l22mg=2π22l3gTalk to our academic expert!
