Solution
Correct Answer:
m a left
A pseudo force (or fictitious force) is introduced when analyzing motion from the perspective of a non-inertial (accelerating) reference frame.
- If the frame is accelerating with aframe relative to an inertial frame, an object of mass m experiences a pseudo force Fp=−maframe.
- The negative sign indicates the pseudo force is always directed opposite to the acceleration of the frame.
- Since the frame moves right, the pseudo force acts to the left with magnitude ma.
This medium difficulty physics question is from the chapter laws of motion, covering the topic of pseudo force. It appeared in the 2025 exam.
