Give me a picture of the problem and i will solve it
Answer:
The value of m is
.
Step-by-step explanation:
If two vectors
and
are perpendicular to each other then their dot product will be zero i.e 
If two vectors
and
are parallel to each other then their cross product will be zero i.e 
Given vectors are a= (3,4) and b=(m,2)
The position vector of
is =
The position vector of
is =
Since
and
are perpendicular.
Then,


⇒3.m +4.2=0
⇒3m+8=0
⇒3m= -8

The value of m is
.
