In this case we observe the block from the elevator itself.Which forces are acting on it?

(1)mg downwards

(2)Normal reaction upwards.

And the block is at rest.So mg=normal reaction

Now observe it from the ground frame.

Forces acting on it are:

(1)mg downwards

(2)Normal reaction upwards.

And the block is accelerating upwards.So N-mg=ma

You can see the difference bewteen the two equations obtained.This force ma is the psuedo force.This acts on the block only in the direction opposite to the direction of motion of the elevator.
