Question

if p vector+Q Vector=R vector and if magnitude of P vector=Q Vector =R vector then what is angle between p vector and q vector​

Answer 1

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 2

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.
