Figure shows the circular motion of a particle. The radius of the circle, the period, sense of revolution and the initial position are indicated on the figure. The simple harmonic motion of the x-projection of the radius vector of the rotating particle 
is:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Let angular velocity of the particle executing circular motion is 
and when it is at Q makes an angle 
as shown in the diagram.
Clearly, 
Now, we can write 
Clearly, this equation represents S.H.M.
