Two bodies A and B hanging in air are tied to the ends of a string which passes over a frictionless pulley. The masses of the string and the pulley are negligible and the masses of two bodies are 2kg and 3kg respectively. (Assume g=(10m/s^2)). Body A moves upwards under a force equal to
The masses of two bodies are 2kg and 3kg respectively. The acceleration of A is
The net force on A will be F=ma=(2\times2)=4N.
