Question

find the component if A vector 3i + 2j along the direction i+j and i-j

Answer 1

Concept Introduction: Vectors are an advanced concept in Physics.

Given:

We have been Given: A vector is

$a = 3i + 2j$

To Find:

We have to Find: Vector along the direction of

$i + j \: and \: i - j$

Solution:

According to the problem, the component along,

$| i + j| = \frac{5}{ \sqrt{2} }$

and

$|i - j| = \frac{1}{ \sqrt{2} }$

Final Answer: The components are

$\frac{5}{ \sqrt{2} } \: and \: \frac{1}{ \sqrt{2} }$
