NEET 2022 Physics Graphs MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The displacement-time graphs of two moving particles make angles of 30° and 45° with the x-axis as shown in the figure. The ratio of their respective velocity is:
A
1 : 2
B
1 : √3
C
√3 : 1
D
1 : 1
Correct Answer
Option A
Detailed Explanation
The velocity is the slope of the displacement-time graph. The slope is proportional to tan(θ). Thus, the ratio of velocities is tan(30°)/tan(45°) = 1/√3, which simplifies to 1:2.
