Content- Vectors questions are a great tool for students trying to comprehend complex mathematical concepts and three-dimensional spaces. These questions offer a comprehensive overview of the topic and practising them will enhance your understanding. To check your answers, go through the detailed explanations for each question.
Solution: When the dot product of two vectors becomes zero, those vectors are perpendicular (the angle between them is $90^\circ$), to each other. Having the components of a vector, we can write the dot product between them as below \[ \vec{a}\cdot\vec{b}=a_x b_x+a_y b_y\] In this problem, we must check each choice separately.
A more elegant solution: we may assume a ⊥ b, otherwise there is no solution. Then the vectors a,b,a × b form an orthogonal basis, hence one can write v as a linear combination v = xa+yb+za×b, x,y,z real numbers We will then take inner products of v with the vectors a,b,a×b. First, v ·a = xkak2. But v ·a = kak, hence x = 1 kak. Also v ...

Solution: It is essential when working with vectors to use proper notation. Always draw an arrow over the letters representing vectors. You can also use bold characters to represent a vector quantity. Vectors A and B are written using the unit vector notation. The magnitude of A is given by: Similarly, the magnitude of B is:
