Given: Two particles p and q start from origin and execute s.h.m along x-axis with same amplitude but with periods 3 seconds and 6 seconds respectively.
To find: The ratio of the velocities of p and q when they are at mean position.
Solution:
- Now let the velocity at the mean position be V(max)
- Then V (max) will be equal to:
V(max) = Aω
- We know that ω = 2π/T
- Now :
V1 = A2π / T1
V2 = A2π / T2
- Here A = A1 = A2.
- Now V1 / V2 = T2 / T1 = 6 / 3 = 2 / 1
Answer:
So the ratio of the velocities of p and q when they are at mean position is 2:1
