A force produces an acceleration `16m^(-2)` in a mass `0.5 kg` and an acceleration `4ms^(-2)` in an unknown mass when appied separately If both the masses are tied together what will be the acceleration under same force ? .

Explanation

Force `F=ma=0.5xx16=8N` when both masses are joined and same force acts, acceleration is given by `a^(1)=(F)/(m+m^(1))=(8)/(0.5+(8//4))=3.2ms^(-1)`
