NEET 2019 Physics Rotational Kinematics MCQ Question
Type: MCQ-numerical-Medium-Class 11
The radius of circle, the period of revolution, initial position and sense of revolution are indicated in the figure. y-projection of the radius vector of rotating particle P is:
A
y(t) = 3cos(3πt/2), where y in m
B
y(t) = 3cos(πt/2), where y in m
C
y(t) = -3cos2πt, where y in m
D
y(t) = 4sin(πt/2), where y in m
Correct Answer
Option B
Detailed Explanation
The y-projection of a rotating vector can be described by a cosine function. Given the period and initial conditions, the correct function is y(t) = 3cos(πt/2).
