To solve the problem, we need to find the value of \( \lambda \) such that the vectors \( 2\hat{i} + 3\hat{j} \), \( 5\hat{i} + 6\hat{j} \), and \( 8\hat{i} + \lambda\hat{j} \) are collinear when they have the same initial point at \( (1, 1) \). ### Step-by-Step Solution: 1. **Identify the Vectors**: The vectors can be represented as: - \( \mathbf{A} = 2\hat{i} + 3\hat{j} \) - \( \mathbf{B} = 5\hat{i} + 6\hat{j} \) ...
