The correct Answer is:
To solve the question, we need to analyze the assertion and the reason provided. ### Step 1: Understand the Assertion The assertion states that for motion in two or three dimensions, the velocity and acceleration vectors must have an angle between \(0^\circ\) and \(90^\circ\) between them. **Analysis**: - Velocity and acceleration can be in the same direction (0°) or in different directions (but still within 90°). - However, they can also be in opposite directions (180°), which means the assertion is not universally true. ### Step 2: Understand the Reason The reason states that for such motion, the velocity and acceleration of an object are always in the opposite direction. **Analysis**: - This is incorrect because velocity and acceleration can be in the same direction (e.g., when an object is speeding up) or at an angle to each other (e.g., when an object is moving in a circular path). They are not always opposite. ### Step 3: Conclusion Since both the assertion and the reason are incorrect, we conclude that: - **Assertion**: False - **Reason**: False ### Final Answer Both Assertion and Reason are False. ---
