A Bob is attached to a long light string the string is deflected by 3 degree initially with respect to vertical the length of the string is 1 metre the value of theta at any time T after the bob released can be approximately at:
θ=3°
l=1m
Since angular SHM occurs So maximum angular displacement is θ.
⇒θ=3° coswt
where w² = lgw
w=✓g/l = ✓π²/l
w=π
θ=3° cos πt
