A particle executes SHM with periodic time of 6 seconds. The time taken for traversing a distance of half the amplitude from mean position is :
Let eqn be x=Asin(wt)
now A2=Asin(wt)
Where
w=2πT
From here t=T12
t=612=12sec.
A particle executes SHM with amplitude 0.2m and time period 24 sec. The time required by it to move from mean position to a point 0.1 m from the mean position is:
