Two bodies of masses m1 and m2 kept on a frictionless surface are pushed by a force F one after the other which produces the acceleration of 4 m/s2and 6 m/s2 in them. What would be the acceleration if the same force is applied when these bodies are tied together ?
a) 1.2 m/s2 b) 4.8 m/s2 c) 2.4 m/s2 d) 2.5 m/s2
