Question

v) Find the magnitude of a vector ⃗ = ⃗ı + 2ȷ⃗​

Answer 1

Given: Vector = i^+2j^

To find: magnitude of the given vector

Step-by-step explanation:

magnitude of i^+2j^= √[(1)²+(2)²]

                                 = √(1+4)

                                  = √5

Answer: Magnitude of given vector = √5
