Question

what is the magnitude of the vector 3 î -4j(cap) + √4k
​

Answer 1

Explanation:

These are orthogonal vectors

Magnitude |v| = √(9 + 16+ 4 )

                       =√29

Answer 2

Answer:

GIVEN:-

vector = 3î -4 j(cap) + √4 k(cap)

vector = 3î -4 j(cap) + 2k(cap)

Ax = 3

Ay = 4

Az = 2

TI FIND:-

magnitude of vector

FORMULA :-

magnitude = √(Ax)²+(Ay)²+(Az)²

SOLUTION:-

magnitude = √(3)²+(4)²+(2)²

= √9+16+4

Magnitude of vector= √29 = 5.38
