Dear shrey,
U need to understand actually what the Psuedo force is.
Psuedo force is a kind of virtual force or U can say an imaginary force that we just pre-assume acting on any object opposite to the net accelration of it for the sake of solving problems in a simple way.
.
Here when the bathtub is accelerated towards right it provides first a Normal force to the ball with net accelration towards right.
And to balnce the Normal force hence U can consider the Psuedo force in opp. of the accln.
that is ma.
Now this becomes a force called psuedo and hence can be balanced.
Therefore,
N = ma would be the Force acting on the ball.
