Q. No.Given below are two statements:
| Assertion (A): | For looping a vertical loop of radius \(r,\) the minimum velocity at lowest point should be \(\sqrt {5gr}.\) |
| Reason (R): | In this event (looping a vertical loop of radius \(r\)), the velocity at the highest point will be zero. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |

Given below are two statements:
| Assertion (A): | The apparent weight of the car is more when it crosses a concave bridge rather than a convex bridge with the same velocity. |
| Reason (R): | The apparent weight of the car means the normal reaction and not the actual weight of the car. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |

Given below are two statements:
| Assertion (A): | In a non-uniform circular motion, the acceleration of the particle is equal to the vector sum of the tangential acceleration and the centripetal acceleration. |
| Reason (R): | The two accelerations are perpendicular to each other. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |

Given below are two statements:
| Assertion (A): | In a non-uniform circular motion, there are two types of accelerations i.e. centripetal and tangential. |
| Reason (R): | Tangential acceleration is responsible to change the speed of the particle moving in a circular motion. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
