Final answer:
The scalar product of two vectors can be found by multiplying their magnitudes and the cosine of the angle between them. In this case, the scalar product of the vectors is 30.5 cos(122°) N.
Step-by-step explanation:
The scalar product of two vectors can be found by multiplying their magnitudes and the cosine of the angle between them. In this case, the scalar product of the vectors can be found by multiplying the magnitude of vector F (30.5 N) with the cosine of the angle θ (122°).
The formula for the scalar product is given by: Scalar Product = |F| * cos(θ).
So, the correct option is c) 30.5 cos(122°) N.
