Important Pseudo Force Questions with Answers

1. The pseudo force direction is always _____ of the acceleration of the frame.

1. in the same direction
2. in the opposite direction
3. neither same nor opposite
4. none of the options

Answer: in the opposite direction

Explanation: The pseudo force acts in the opposite direction to the acceleration of the frame.

1. 1
2. 0
3. -1
4. Always negative

Answer: b) 0

Explanation: The work done by the pseudo force is always zero.

3. Choose the correct answer: The force produced due to the interaction between the objects is known as ______

1. Pseudo force
2. Real force

Answer: b) Real force

Explanation: Real force is produced when the objects interact.

4. Choose YES or NO: Is pseudo one of the fundamental forces?

1. YES
2. NO

Answer: b) NO

Explanation: Pseudo is a non-fundamental force.

5. Which force obeys Newton’s law of motion?

1. Pseudo force
2. Real force

Answer: b) Real force

Explanation: Real forces obey Newton’s law of motion.

6. Give an example of pseudo force.

Bus moving on a straight road accelerating in the forward direction, a person of mass ‘m’ experiences a pseudo force acting backward of magnitude ‘ma’.

7. Name fundamental forces.

Electromagnetic, gravitational, strong, and weak forces are the fundamental forces.

8. State true or false: Coriolis force is the invisible force.

1. TRUE
2. FALSE

Answer: a) TRUE

Explanation: The Coriolis force is the invisible force that appears to deflect the objects.

Gustave-Gaspard Coriolis, a French engineer-mathematician described the Coriolis effect.

10. Choose YES or NO: Is pseudo force considered a real force?

1. YES
2. NO

Answer: b) NO

Explanation: Since no physical interaction is involved, pseudo force is a fictitious force and is not considered a real force.
