Question

if P+Q=R and p²+Q² = R² then find the angle between the vector
P and Q​

Answer 1

Step-by-step explanation:

2,000 because 753 down down then up yeah

Answer 2

Step-by-step explanation:

Given, →P+→Q=→R

So, we can write,

∣∣∣→R∣∣∣=√P2+Q2+2PQcosθ,where θ is the angle between the two vectors.

Or, R2=P2+Q2+2PQcosθ

Given, P2+Q2=R2

So, R2=R2+2PQcosθ

Or, 2PQcosθ=0

So, cosθ=0

Or, θ=90∘
