- B. 4
- C. 6
- D. 8
Explanation
The dot product of two vectors is calculated by multiplying their corresponding components and then adding those products together.So, for the vectors (1, 1, 1) and (2, 2, 2), the dot product would be:Vectors are i+j+k and 2i+2j+2k(i+j+k).(2i+2j+2k) = (1x2) + (1x2) + (1x2) = 2 + 2 + 2 = 6
