11.A particle is executing simple harmonic motion of amplitude 10cm. Its time period of oscillation is π seconds. The velocity of the particle when it is 2 cm from extreme position is?
A.10 cm/s
B.12 cm/s
C.16√16 cm/s
D.16 cm/s
Answer:  Option  B
Explanation:

v=2π/T×√(A2-y2)
v=2π/π √(102-82)
=2×6=12cm/s.
