Question

The phase of a particle in SHM at time t is Π/6.
The following inference is drawn from this:
(1), The particle is at x = a/2 and moving in
+ X-direction
(2) The particle is at x = a/2 and moving in
16 - X-direction
(3) The particle is at x = -a/2 and moving in
+ X-direction
(4) The particle is at x = -a/2 and moving in
- X-direction​

Answer 1

Explanation:

X = a sin wt

wt = π /6

2π /T t = π/ 6

t = T / 12

it is ⅓ of T/4.thus the particle is at x= a/2 and moving in + X - direction.
