Two vectors `vecP` and ` vecQ` are having their magnitudes in the ratio `sqrt(3) :1. Further । vecP+vecQ । =। vecP - vecQ। ` then the angle between the vectors `(vecP+ vecQ)` and `(vecP - vecQ)` is

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the given information
We are given two vectors \( \vec{P} \) and \( \vec{Q} \) with their magnitudes in the ratio \( \sqrt{3} : 1 \). This means we can express their magnitudes as:
\[ |\vec{P}| = \sqrt{3}k \quad \text{and} \quad |\vec{Q}| = k \]
for some scalar \( k \).
