Question

If I and j are unit vectors along x and y axis then what is the magnitude and direction of I+j and i-j

Answer 1

Answer:

Explanation:

magnitude of i+j =√(1^2+1^2)=√2

for i-j=√(1^2+(-1)^2)=√2

i+j makes 45° with coordinate axes and i-j makes -45° with coordinate axes

both are perpendicular to each other
