Question

calculate the value of k cap .I cap
​

Answer 1

Answer:

0

Explanation:

Dear student,

we know that k cap and I cap are two unit vectors whose direction is along z axis and x axis respectively and are also perpendicular to each other

We also know that Dot product is given by:

a (bar). b (bar) = |a|•|b|•cosθ

Here a(bar ) is k cap and b(bar) is I cap.

|a|=1

|b|=1

θ=90°

therefore,

k cap . I cap= 1.1.cos(90°)=1.1.0=0

Hope this helps you!!

Please mark it as brainliest!!

Cheers.
