If assertion is incorrect, but reason is correct.
Q.1. Assertion: A potter makes pots of different sizes and shapes from kneaded clay. Reason: Force may bring about change in the size or shape of an object.
Q.2. Assertion: When same force is applied for same time, to both car and truck. The car picks up a greater speed than truck in that time. Reason: The magnitude of force needed depends on the mass of object and value of change of speed.
Q.3. Assertion: In tug a war, when both the teams pull the rope, with equal and opposite force the rope will remain stationery. Reason: The unequal force may not bring about change in state of rest.
Q.4. Assertion: A ball rolling along the ground, gradually slows down and finally comes to rest. Reason: This happens due to force of friction between the ball and the ground.
Q.5. Assertion: As we move to higher altitudes, breathing can become difficult. Reason: At higher altitude there is decrease in the atmospheric pressure.
Q.6. Assertion: We can drink cold drink from a bottle with help of straw. Reason: The pressure inside the straw is more than the pressure outside.
Q.7. Assertion: It is difficult to carry a bag with narrow straps as compared to carry the same bag with broader strap. Reason: When the same force acts over a small area its effect is more.
Q.8. Assertion: Falling of rain drops is a contact force. Reason: Gravitational force is an example of contact force.
Q.9. Assertion: Pressure = force /area Reason: P =Force /area, here F force is thrust.
Q.10. Assertion: Force can be added in pressure. Reason: Force and pressure has same magnitude.
