. Define Modulus of a vector

Best Answer

The modulus of a vector means the length of the vector. It is always positive and has no direction.

Note:

i. Scalar quantity may be negative e.g. charge, electric current, potential energy, work etc.

ii. Scalar quantity are direction independent e.g pressure, electric current, surface tension etc.

iii. Vector quantities are direction dependent e.g. force, velocity and displacement.
