Question

Find magnitude of given vector is B = 3i + 4j +k

Answer 1

Answer:

|B| = √ (3)^2 +(4)^2+(1)^2.

= √9+16+1

= √26.

Hope it helps you.

Answer 2

Answer:

√26 units

Explanation:

hey mate

given vector:

B=3i+4j+k

we know that the magnitude of the vector,Ai+Bj+Ck ia given by √(A²+B²+C²)..

so,the magnitude of vector B (|B|)= √(3²+4²+1²)

=√26 units

some additional information:

*A vector is the physical quantity which has both magnitude and direction and must necessarily obey vector Algebra viz.law of addition.

*a vector is represented by either a bold letter or by giving an arrow on vector.

*a vector can be resolved into its components.

*the magnitude of a vector is represented by inserting the vector in between two parallel lines called pipes.e.g:

|A| represents the magnitude of the vector A.
