Question

the question of displacement of a body executing SHM is X is equal to X not Sin Omega T what is initial phase
​

Answer 1

Answer:

Explanation:

Correct option is

A

0.33sec

x=Asin(2πt+  

3

π

​

)

Velocity is maximum at mean position i.e. x=0

⇒sin(2πt+  

3

π

​

)=0

⇒(2πt+  

3

π

​

)=0,π,2π,3π....

if we take (2πt+  

3

π

​

)=0, time will come negative which is not possible. So we take (2πt+  

3

π

​

)=π

⇒t=  

3

1

​

s=0.33s

for other solutions, we will get higher values of time. but Since it is asking for the first time after t=0, the required solution will be t=0.33s
