Question

if v 1 bar is equal to 3 ICAP + 4 j cap + K cap and V2 bar is equals to ICAP - 2 J cap - 4 cap determine the magnitude of V1 bar Plus V2 bar​

Answer 1

Explanation:

|v1+ V2| =√ I cap value ²+ j cap value ² + k cap value ²

=√ (3+1)²+ ( 4 -2)² + (1-4)²

√16+ 4+ 9 =√29 ans

Answer 2

Explanation:

|3i^ + 4j^ + k^ + i^- 2j^- 4k^| = | 4i^ + 2j^ -3k^|

magnitude will be

√4^2 + 2^2 + (-3)^2 = √29 ans is correct one
