Question

Does resultant of vectors mean the sum of vectors with appropriate signs.

Answer 1

Dear student,
Yes your approach is true.
The resultant vector is the vector that 'results' from adding two or more vectors together. There are a two different ways to calculate the resultant vector.

Methods for calculating a Resultant Vector
The head to tail method to calculate a resultant which involves lining up the head of the one vector with the tail of the other.

The parallelogram method to calculate resultant vector. This method involves properties of parallelograms but, in the end, boils down to a simple formula.
Regards.
