A particle A of mass 3 kg lies on a smooth plane inclined at 30∘ 30^\circ\,30∘ to the horizontal. It is connected by a light inextensible string passing over a smooth pulley at the top of the plane to a hanging particle B of mass 2 kg. The system is released from rest, with B moving downwards. 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.
