Verified Answer :

a+b= ? 
3i +3j + (3i -3j) = ? 
3i + 3j + 3i -3j =? 
= 6i + 0j

Answer:

Resultant, \(R=6i\)

Explanation:

Given that,

Vector \(A=3i+3j\)

Vector \(B=3i-3j\)

Vectors are those quantities that have both magnitude and direction. We need to find the resultant A and B. It can be done by adding two vectors such that,

\(R=A+B\)

\(R=(3i+3j)+(3i-3j)\)

\(R=6i\)

So, the resultant of A and B is 6i. Hence, this is the required solution.
