Question

find the angle between two vectors.p vector and q vector.if the resultant of the vector is given by r^2=p^2+q^2​

Answer 1

Answer:

Angle is 90°

Explanation:

As we know that R2= P2+Q2+2PQcos theta

Here we have to find theta

According to q we have R2= PE+Q2

So means 2PQ cos theta = 0

means cos theta = 0

so we know that cos 90° = 0

so theta = 90°

So the angle between both vectors is 90°
