The Exercise 10.4 of NCERT Solutions for Class 12 Maths Chapter 10- Vector Algebra is based on vector (or cross) product of two vectors. The concept of distributivity of vector product over addition is also explained before this exercise. The magnitude of the vector product of two vectors can be constructed by taking the product of the magnitudes of the vectors times the sine of the angle (<180 degrees) between them. There are problems present in this exercise which are based on this definition of vector products as well.
