Three blocks of masses \[{{m}_{1}},\,{{m}_{2}}\] and \[{{m}_{3}}\] are connected by massless strings as shown on a frictionless table. They are pulled with a force \[{{T}_{3}}=40\,N\]. If \[{{m}_{1}}=10\,kg,\,{{m}_{2}}=6\,kg\] and \[{{m}_{3}}=4\,kg\], the tension \[{{T}_{2}}\] will be               [MP PMT/PET 1998]
