JEE Mains · Maths · STD 12 - 10. vector algebra
If the projections of a line segment on the \(x, y\) and \(z-\) axes in \(3-\) dimensional space are \(2, 3\) and \(6\) respectively, then the length of the line segment is
- A \(12\)
- B \(7\)
- C \(9\)
- D \(6\)
Answer & Solution
Correct Answer
(B) \(7\)
Step-by-step Solution
Detailed explanation
Length of the line segment \( = \,\sqrt {{{\left( 2 \right)}^2} + {{\left( 3 \right)}^2} + {{\left( 6 \right)}^2}} = 7\)
