- What is the distance of the point (p, q, r) from the x-axis? [CBSE Sample Paper 2017]
- If a line makes angles 90° and 60° respectively with the positive directions of x and y axes, find the angle which it makes with the positive direction of z-axis. [Delhi 2017]
- If a, b and c are mutually perpendicular vectors of equal magnitudes, show that the vector a + b + c is equally inclined to a, b and c. Also, find the angle which a + b + c makes with a or b or c. [Delhi 2017]
- Find the position vector of a point which divides the join of points with position vectors a – 2b and 2a + b externally in the ratio 2:1. [Delhi 2016]
- The two vectors j + k and 3i – j + 4k represent the two sides AB and AC, respectively of a triangle ABC. Find the length of the median through A. [Delhi 2016]
- Find a vector in the direction of a = i – 2j that has magnitude 7 units. [Delhi 2015C]
- If a and b are unit vectors, then what is the angle between a and b so that √2 a – b is a unit vector? [Delhi 2015C]
- If a = 7i + j – 4k and b = 2i + 6j + 3k, then find the projection of a on b. [Delhi 2015]
- If a line makes angles 90°, 60° and θ with x, y and z-axis respectively, where θ is acute, then find θ. [Delhi 2015]
