Question

the vector having a magnitude of 10 and perpendicular to the vectors 3i -4j is
please answer it fast
it is very urgent ​

Answer 1

Answer:

Explanation:

Magnitude of vector is,

10

And it is perpendicular to vector ,

3i-4j

LET THEVECTOR BE

ai + bj

IF THEY ARE PERPENDICULAR THEN

THEIR DOT PROUCT IS 0

a.b=0

(3i-4j) (ai+bj)=0

3a - 4b =0

3a= 4b

a/b= 4/3

Then the vector is

(4i+3j)10
