Solution

The correct option is D downward
The pseudo force in a non-inertial frame is given by, ${∣ ∣ \to F ∣ ∣}_{p s e u d o} = M a$
where, M = mass of an object in that frame
a = acceleration of the frame
Thus, F = 50 $\times$ 25 N
= 1250 N
The direction will be opposite to the acceleration of the frame. In this case it is vertically downwards.
Therefore, ${\to F}_{p s e u d o} = 1250 N,$ downwards.
