Particles A A\,A and BBB, of masses 3 kg and 2 kg respectively, are connected by a light inextensible string passing over a smooth fixed pulley. The particles are released from rest with A A\,A hanging lower than BBB. Use g=9.8 m s−2g=9.8\text{ m s}^{-2}g=9.8 m s−2.
Find the magnitude of the acceleration of the particles.
Find the tension in the string.
