Perhatikan vektor gaya di bawah!

Jika nilai begin mathsize 14px style F with rightwards arrow on top equals 2 space straight N end style, nilai komponen vektor ke arah sumbu X dan sumbu Y yang tepat adalah...

  1. begin mathsize 14px style stack F subscript x with rightwards arrow on top equals 1 space straight N stack F subscript y with rightwards arrow on top equals square root of 3 space straight N end style 

  2. begin mathsize 14px style stack F subscript x with rightwards arrow on top equals 1 space straight N stack F subscript y with rightwards arrow on top equals negative square root of 3 space straight N end style  

  3. begin mathsize 14px style stack F subscript x with rightwards arrow on top equals square root of 3 space straight N stack F subscript y with rightwards arrow on top equals 1 space straight N end style  

  4. begin mathsize 14px style stack F subscript x with rightwards arrow on top equals negative 1 space straight N stack F subscript y with rightwards arrow on top equals negative square root of 3 space straight N end style 

  5. begin mathsize 14px style stack F subscript x with rightwards arrow on top equals square root of 3 space straight N stack F subscript y with rightwards arrow on top equals negative 1 space straight N end style
