Question

Which is true for the vector provided the only position coordinates given?

(a) (Final position coordinates + initial positions coordinates) gives the vector form of the vector

(b) (Final position coordinates – initial positions coordinates) gives the vector form of the vector

(c) (Initial positions coordinates – Final position coordinates) gives the vector form of the vector

(d) (Initial positions coordinates + Final position coordinates) gives the vector form of the vector

The question was posed to me at a job interview.

My query is from Cartesian Vectors in division Force Vectors of Engineering Mechanics

Answer 1

Right option is (b) (Final position coordinates – initial positions coordinates) gives the vector form of the vector

The explanation is: We find the vector form from subtracting the initial position coordinates from final position coordinates. Not from subtracting the final position coordinates from initial position coordinates.
