1.	A ball of mass 1 kghangs in equlibrium from two stings OAand OBin the diagram calcualte the tensions in stings OAand OB take g=10ms^(-2)
Answer» Solution :Givenmassof the ball `=1kg` `g=10 ms^(-1)` Variousforces actingat the point O are atshownin thediagram .Thethree forcesare inequilibrium.usingLamis THEOREM `(T_(1))/(sin150^(@)) = (T_(2))/(SIN 120^(@))= (10)/(sin 90^(@))` and `T_(1) 10 sin 30^(@) = 10 xx 0.5=5N` and `T_(2) =10 sin 60^(@)=10 xx (SQRT(3))/(2)` `=5sqrt(3) N`
