Periodic Motion :: Discussion


6.A particle executes simple harmonic motion between x = -A and x = +A. The time taken for it to go from 0 to A/2 is T1 and to go from A/2 to A is T2. Then?
A.T1 < T2
B.T1 > T2
C.T1=T2
D.T1=2T2
Answer:  Option  A
Explanation:

x=Asinωt
For x=A/2,
sinωT1=1/2
ωT1=π/6 or T1=π/2ω
For x=A,
sinω(T1+T2)=1
T1+T2=π/2ω
T2=π/2ω-π/6ω=π/3ω=2T1.
