Question

The two vectors `A=2hat(i)+hat(j)+3hat(k)` and `B=7hat(i)-5hat(j)-3hat(k)` are :-
the sum and the differnce of two vectors `vec(A)` and `vec(B)` are ________ and ________ respectively.

Answer 1

Correct Answer - `9hat(i)-4hat(j)+0hat(k),-5hat(i)+6hat(j)+6hat(k)`
`vec(A)+vec(B)=9hat(i)-4hat(j)+ohat(k)`
`vec(A)-vec(B)=-5hat(i)+6hat(j)+6hat(k)`
