Question

if A = 4i - 3j and B = 6i + 8j , then A + B is ?

Answer 1

if A = 4i - 3j

B = 6i + 8j ,

then A + B = 4i - 3j + 6i + 8j

= 10i + 5j

hope you have got the answer if yes then follow me

Answer 2

Answer:

$\displaystyle \longrightarrow \vec{\text{A}}+\vec{\text{B}}=10\hat{i}+5\hat{j}$

Explanation:

Given :

$\displaystyle \vec{\text{A}}=4\hat{i}-3\hat{j}$

$\displaystyle \vec{\text{B}}=6\hat{i}+8\hat{j}$

We are asked to find :

$\displaystyle \vec{\text{A}}+\vec{\text{B}}$

$\displaystyle \vec{\text{A}}+\vec{\text{B}}=4\hat{i}-3\hat{j}+6\hat{i}+8\hat{j}$

$\displaystyle \longrightarrow \vec{\text{A}}+\vec{\text{B}}=(4+6)\hat{i}+(8-3)\hat{j}$

$\displaystyle \longrightarrow \vec{\text{A}}+\vec{\text{B}}=10\hat{i}+5\hat{j}$

Hence we get required answer!
