NEET 2018 Physics Average Speed and Velocity MCQ Question
Type: MCQ-numerical-Medium-Class 11
A toy car with charge q moves on a frictionless horizontal plane surface under the influence of a uniform electric field E. Due to the force qE, its velocity increases from 0 to 6 m/s in one second duration. At that instant the direction of the field is reversed. The car continues to move for two more seconds under the influence of this field. The average velocity and the average speed of the toy car between 0 to 3 seconds are respectively
A
2 m/s, 4 m/s
B
1 m/s, 3 m/s
C
1 m/s, 3.5 m/s
D
1.5 m/s, 3 m/s
Correct Answer
Option B
Detailed Explanation
The average velocity is calculated as the total displacement over time, and the average speed is the total distance over time.
