Question

the angle made by the vector A=i+j with z-axis is

Answer 1

Answer:90°

Explanation:As the resultant will lie in x-y plane ......and z axis is perpendicular to every vector in xand y plane ......so ....the theta is 90 degrees

Answer 2

Answer:

Explanation:

Explanation:

ı^ is a unit vector parallel to the x−

axis.

ȷ^

is a unit vector parallel to the y−

axis.

So any linear combination of those two αı^+βȷ^

lies is in the x−y

plane.

The z−

axis is perpendicular to all the vectors in the x−y

plane.

So ı^+ȷ^

makes an angle of 90∘ with the the z−axis
