Question

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

Answer 1

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

Answer 2

Resultant,
`R=6i`

Step-by-step 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.
