The vector in the direction of the sum of the vectors is
- A Perpendicular to plane
- B Parallel to - plane
- C Parallel to plane
- D Perpendicular to plane
Answer & Solution
Correct Answer
(C) Parallel to plane
Step-by-step Solution
Detailed explanation
Given, a→=2i^-2j^+5k^ and b→=-2i^+5j^-3k^ Now, a→+b→=2i^-2j^+5k^+-2i^+5j^-3k^=3j^+2k^ As, a→+b→.i^=0 As there is no i^ component in a→+b→ & sum is in the linear combination of j^ & k^ So, it is parallel…
