Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Scalar is defined as a quantity which can be expressed by a single number that represents its magnitude. for ex. temperature. Scalar field is hence defined as a region where at every point of it, a scalar function has a defined value. for ex. temperature distribution in a rod. Vector is defined as a quantity which is expressed by both magnitude and direction. for ex. velocity. Vector field is hence defined as a region where at every point of it, a vector function has a defined value. for ex. velocity of flowing liquid.
