Answer:
if the resultant of two vectors P & Q is (P+Q),then angle between P&Q is , The angle between will be 0°. R is resultant; theta is angle between P & Q; R,P,Q are in Mod value

Answer:
Magnitude Sum of Two vectors Vector P and Vector q is given by
r^2 =p^2+q^2+2pqcos($) __________________________(i)
here $ indicates angle between them.
We are given
r=p+q
so Squaring both the sides we get
r^2=p^2+q^2+2pq ______________________(ii)
From (i) and (ii) we can write
p^2+q^2+2pqcos($)=p^2+q^2+2pq
therefore 2pq=2pqcos($)
cos($)=1
therefore $=0
So angle between p vector and q vector is 0 degree.
