1here N and mg are both acting on the block.. so this is not an action-reaction pair..
A block of mass m is kept on a rough horizontal floor having coefficient of friction μ A constant horizontal force F is applied on the block towards right due to which it is moving with a constant acceleration a.Free body diagram of the object is shown in the figure
my doubt does the force mg is the action and N is reaction

1no bcos N is internal force of the system
ie mass & floor system(nt so sure)
1@ram reaction to wat & i dont thnk friction is a reaction force

62sky's answer is perfect.. the others have flaws!
There will be another normal on the fbd of the ground..
That normal reaction and this normal reaction will together form the action reaction pair :)

62Ramkumar.. frictional force is also an action reaction pair.. and u are correct to have observed that :)
But it is not the reaction to N.. (If that is what u are saying it is a wrong observation!)
