Figure shows two blocks each of mass 2kg , connected by a string passing over two pulleys. One block rests on a smooth horizontal surface and theother blockhangs vertically. Assume pullyes to be frictionless and massless. What is the tension in the string?

1.	Figure shows two blocks each of mass 2kg , connected by a string passing over two pulleys. One block rests on a smooth horizontal surface and theother blockhangs vertically. Assume pullyes to be frictionless and massless. What is the tension in the string?
Answer» SOLUTION :From the free-body diagram of vertically HANGING 2kg block, 2g-T=2a……(i) CONSIDERING the 2kg block on the horizontal SURFACE, T=2a………(ii) COMBINING (i) and (ii) 2g-T =T or 2T=2g or T=g Newton =`9.8N`
