Direction: In each of the following questions, four words have been given, out of which three are alike in some manner and the fourth one is different. Choose out the odd one.
Show answer & explanation
Correct answer: A
Explanation
Answer: Acceleration
Logic: Three of these are scalar quantities (have only magnitude, no direction), while one is a vector quantity (has both magnitude and direction).
- Interest → scalar (just a magnitude, e.g., ₹500)
- Age → scalar (just a magnitude, e.g., 25 years)
- Mass → scalar (just a magnitude, e.g., 60 kg)
- Acceleration → vector (has both magnitude and direction, e.g., 5 m/s² downward)
So, Acceleration is the odd one out, as the other three are scalar quantities.
