Question

If i,j and k are unit vectors along x,y and z axis respectively,find i.(j*k)​

Answer 1

To find the dot product of vectors, you can use the distributive property:

i · (j × k) = (i · j) × k

Since i is a unit vector along the x-axis and j is a unit vector along the y-axis, the dot product of i and j (i · j) is zero because they are perpendicular to each other. So:

i · (j × k) = (0) × k = 0

So, i · (j × k) equals 0.
