Question

What is the phase difference between two simple harmonic motions represented by `x1=A sin(omegat +pi/6)` and `x2=A cos omegat` A. `pi/6` B. `pi/3` C. `pi/2` D. `(2pi)/3` ?

Answer 1

`B`>

Explanation:

`A cos omegat` can be written as `A sin(pi/2 +omegat)`

So, `del phi =(pi/2 +omegat -omegat-pi/6) =pi/3`
