Questions
A mass M of 100 kg is suspended with the use of strings A, B and C as shown in fig. Here W is
vertical wall and of is rigid horizontal rod. The tension in string B is
detailed solution
Correct option is A
Let T be the tension in the string C. ThenT cosâ¡45â=Mg â¦(1)and T sinâ¡45â= tension in B â¦(2)From eq. (i), T=Mgcosâ¡45â=2MgFrom eq. (ii), tension in B=Tsinâ¡45â=(2Mg)Ã(1/2)=Mg=100g newton.Talk to our academic expert!
