Question

The magnitude of resultant of vectors A=10i+15j and B=5i is

Answer 1

Answer:

18.7

Explanation:

Resultant=√a^2+b^2

Answer 2

Answer:15√2

Explanation:A=10i+15j;B=5i

resultant of two vectors=A+B

                                         =(10i+15j)+(5i)

                                         =(15i+15j)

Magnitude of two vectors=√15²+15²

                                          =√225+225

                                          =15√2
