Answer:

There are two types of vector products. One is called scalar product or dot product which is denoted by A.B and is defined as a scalar |A||B| cos theta, where theta is the angle between A and B measured from A towards B in the positive direction. If this product is zero, then cos theta is 0. Then theta = 90°.

Angle between vector A and vector B is 90^{o}.

Explanation:

  • Dot product of two vectors is also called scalar product of vectors.
  • Dot product is expressed as multiplication of magnitude of both the two vectors and the cosecant value of angle between them.

Here,

  • A · B =|A| |B| cos \alpha, where α is the angle between the vectors A and B.
  • The result of dot product is a scalar number which is why it is called scalar product of vectors.
  • Physical significance of dot product is the length of the projection of A onto B multiplied by the length of B.
  • For the dot product to be zero, angle should be equal to 90^{o} as cos90^{o} =0.
