Three electromagnetic waves travel through a certain point P along an x axis. They are polarized parallel to a y axis, with the following variations in their amplitudes. Find their resultant at P.
`E_(1)=(8.00 mu V // m)sin[(2.0 xx 10^(14) "rad" // s)t]`
`E_(2)=(5.00 mu V // m)sin[(2.0 xx 10^(14) "rad" // s)t+55.0^(@)]`
`E_(3)=(5.00 mu V // m)sin[(2.0 xx 10^(14) "rad" // s)t-55.0^(@)]`

Explanation

`(13.7 mu V // m) sin[(2.0 xx 10^(14) rad // s)]`
