    46:18 Vectors a and c are collinear but not equal.
    Since, two vectors are said to be equal if they have the same magnitude as well as the same direction. But here vectors a and c are equal in magnitude but different in direction. So we can't call them as equal vectors, but they are collinear.

      As equal vector implies - same magnitude and same direction.
      a and c vector will have same magnitude but their directions are opposite

    Sir when you are explaining types of vector by example, there can vector a and vector c be considered as collinear but not equal?

      We take area as vector in physics. It's direction is outward and perpendicular to the surface. but in Mathematics area is assumed as scaler quantity.

    Area is a vector quantity calculated perpendicular to the surface in both directions in 2-D figures and is calculated outward normal incase of closed or 3-D figures......is saal physics me padha hoga sabne🙂

    46:17 sir, vector a & c are colinear but not equal
    reason : a and c are parallel so it is colinear but they have opposite direction , they are not equal.??
