MCQ

These are the component forms of vectors s\vec{s} and t\vec{t} where, s=(1,4)\vec{s}=(-1,-4) and t=(2,2)\vec{t}=(2,-2) Bodhi and Bram tried to find the sum of the vectors.

Bodhi tried adding the vectors component-wise:

(1,4)+(2,2)=(1+2,4+(2))=(1,2)(-1,-4)+(2,-2)=(-1+2,-4+(-2))=(1,-2)

Bram tried adding the vectors using the parallelogram rule. He drew the following diagram and concluded that the sum is (3,2)(3,2).

Since they did not get the same answer, they figured at least one of them is wrong. Who made a mistake?

Select all that apply :

Both are wrong

Bram
