A particle A of mass 4 kg lies on a smooth horizontal table. It is connected by a light inextensible string passing over a smooth pulley at the edge of the table to a hanging particle B of mass 2 kg. The system is released from rest. Take g=9.8g=9.8g=9.8 m s−2^{-2}−2.
Find the acceleration of the particles.
Find the tension in the string.
