- What is the distance of the point (p, q, r) from the x-axis? [CBSE Sample Paper2017]
- 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 3**i**–**j**+ 4**k**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**– 2**j**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**= 7**i**+**j**– 4**k**and**b**= 2**i**+ 6**j**+ 3**k**, 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]
- If
**r**= x**i**+ y**j**+ z**k**, find (**r**×**i**).(**r**×**j**) + xy. [Delhi 2015]
