Q:A uniform metre stick of mass 200g is suspended from the ceiling through two vertical strings of equal lengths fixed at the ends.A small object of mass 20g is placed on the stick at a distance of 70cm from the left end.Find the tensions in the two strings?

Dear Varun

 

 

T1+T2 =220g

moment balance at point B

T1 *100 -200g *50 -20g *30 =0

T1 =106g

T2=220-T1= 114g
