The push to the right is due to the is due to the acceleration of the observer's frame of reference - the capsule - to the left. This could be due to an acceleration of the capsule in a straight line towards the left or due to the circular motion of the capsule, in which case it is the centripetal acceleration

The force to the right is a reality in the observer's reference frame.

Similar pseudo force is experienced in a lift which accelerates up or down, and in an accelerating vehicle.
