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 the other 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 the other 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 2 KG block, `2g - T=2a`...... (i) considering the 2 kg block on the horizontal SURFACE . `T=2a`............ (ii) combining (i) and (ii) ` 2g -T=T or 2T = 2g or T=g ` Newton =9.8 N
