Multiple Choice & Matching Questions on Force, Pressure, and Magnetism

Here are the answers to the questions:

Choose the correct answers:

1. Liquid pressure is least at the bottom of the container. ❌ Incorrect. Liquid pressure is greatest at the bottom of the container because it increases with depth.
2. Force of friction is a non-contact force. ❌ Incorrect. Friction is a contact force, as it acts between surfaces that are in contact.
3. North pole of the magnet repels the south pole of the another magnet? ❌ Incorrect. Opposite poles (North and South) attract each other. Like poles repel.
4. Gravitational force is a contact force. ❌ Incorrect. Gravitational force is a non-contact force, acting between objects even when they are not touching.
5. Force can change the state of motion of the body. ✅ Correct. An unbalanced force can change an object's speed or direction of motion.

Match the terms given in column I with these given in column II:

• 1. Pressure matches with Force/Area
• 2. Gravitational force matches with Non Contact Force
• 3. Atmosphere Pressure matches with Working of a dropper
• 4. Force matches with Pull or Push
• 5. Friction Force matches with Opposes the motion of the body.

Here is the complete matching:

1. Pressure - Force/Area
2. Gravitational force - Non Contact Force
3. Atmosphere Pressure - Working of a dropper
4. Force - Pull or Push
5. Friction Force - Opposes the motion of the body.
