FAQs on Multiplication of a Vector by a Scalar Components of a Vector Video Lecture - Mathematics (Maths) for JEE Main & Advanced
| 1. What is the meaning of multiplying a vector by a scalar? |  |
Ans. Multiplying a vector by a scalar means scaling the vector by a specific value. It involves multiplying each component of the vector by the given scalar value.
| 2. How does multiplication by a scalar affect the direction of a vector? | |
Ans. Multiplying a vector by a scalar does not change its direction. It only changes the vector's magnitude or length while keeping the same direction.
| 3. Can a scalar be negative when multiplying it with a vector? | |
Ans. Yes, a scalar can be negative when multiplied with a vector. When a scalar is negative, it results in reversing the direction of the vector while maintaining its magnitude.
| 4. What happens when a vector is multiplied by zero? | |
Ans. When a vector is multiplied by zero, the result is a zero vector. This means that all the components of the vector become zero, resulting in a vector with no magnitude and no direction.
| 5. Can a vector be multiplied by a complex scalar? | |
Ans. Yes, a vector can be multiplied by a complex scalar. The complex scalar would multiply each component of the vector, just like a real scalar, resulting in a complex-valued vector with both real and imaginary parts.
