A vector has magnitude and direction (i) Does it have a location in the space ? (ii) Can it vary with time ? (iii) Will two equal vectors ` vec a` and `vec b` different locations in space necessarily have identical physical effects ? Give examples in support of your answer.

Explanation

To solve the question, we will break it down into three parts as specified in the question.

### Solution:

**Part (i): Does a vector have a location in space?**

A vector is defined by its magnitude and direction. However, it does not have a specific location in space. This is because two vectors can have the same magnitude and direction but can be positioned at different points in space. For example, a vector representing a force of 5 N acting to the right can be applied at different locations, such as at point A or point B. Therefore, we conclude that a vector does not have a fixed location in space.
