Question:medium

Let the position vectors of three vertices of a triangle be \( \overrightarrow{p} = 4\hat{i} + \hat{j} - 3\hat{k} \), \( \overrightarrow{q} = -5\hat{i} + 2\hat{j} + 3\hat{k} \), and \( \overrightarrow{r} = -5\hat{i} + 3\hat{j} + 2\hat{k} \). Then \( \alpha + 2\beta + 5\gamma \) is equal to:

Show Hint

For problems involving position vectors and the centroid or orthocenter, use the properties of these points to form relationships between the coefficients and solve for the desired value.

Show Solution

The Correct Option is C

Solution and Explanation

The sum \( \alpha + 2\beta + 5\gamma \) is calculated utilizing the centroid and orthocenter properties with the given triangle vertex position vectors. Final Answer: \( \alpha + 2\beta + 5\gamma = 3 \).
