Question

The projection of the line segment joining the points \( (2, 1, -3) \) and \( (-1, 0, 2) \) on the line whose direction ratios are \( 3, 2, 6 \) is

• A. \( \frac{19}{7} \) units
• B. \( \frac{17}{7} \) units
• C. \( \frac{11}{7} \) units
• D. \( \frac{15}{7} \) units

Hint:

Projection formula: \( \frac{|(x_2-x_1)a + (y_2-y_1)b + (z_2-z_1)c|}{\sqrt{a^2+b^2+c^2}} \).

Answer 1

The Correct Option is C
