Assertion: Two vectors are said to be like vectors if they have same direction but different magnitude. Reason: Vector quantities do not have specific direction.

If the magnitude of sum of two vectors is equal to the magnitude of difference of the two vectors, the angle between these vectors is

The cross product of two vectors gives null vector when the vectors enclose an angle to

Show that if two vectors are equal in magnitude, their vector sum and difference are at right angles.

Two vectors , having same magnitude but opposite direction are called (a) equal vectors (b) negative vectors (c) unit vectors (d) null vectors
