What is the resultant of a and b if a = 3i 3j and b = 3i − 3j?
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.
