## When the dot product of two vectors are zero then the two vectors are?

orthogonal

Two nonzero vectors are called orthogonal if the the dot product of these vectors is zero.

**Is the vector product of two non zero vectors is zero then vectors must be?**

The dot product of two non zero vectors can only be zero when they are perpendicular to each other and in such a case their cross product becomes maximum or in other words their cross product is equal to the product of their magnitudes. If the dot product is 0 that means they are perpendicular (90 degree angle).

**What is the product of two scalar vectors?**

The scalar product of two vectors is defined as the product of the magnitudes of the two vectors and the cosine of the angles between them.

### What if the dot product is 0?

A dot product of two vectors is the product of their lengths times the cosine of the angle between them. If the dot product is 0, then either the length of one or both is 0, or the angle between them is 90 degrees.

**What happens when dot product is 0?**

**Under what condition is the scalar product of two non-zero vectors zero *?**

When the two vectors are at at right angle to each other then their scalar product is 0 .

## Which one of the following is a null vector?

(c) The acceleration vector of a particle in uniform circular motion averaged over one cycle is a null vector.

**How do you find the vector product of two vectors?**

Vector Product of Two Vectors

- If you have two vectors a and b then the vector product of a and b is c.
- c = a × b.
- So this a × b actually means that the magnitude of c = ab sinθ where θ is the angle between a and b and the direction of c is perpendicular to a well as b.

**What happens when you add a vector to a zero vector?**

When a vector is added to a zero vector, the resulting vector is the same as the vector that was added to the zero vector. Similarly, when a zero vector is subtracted from a vector, the resulting vector is the same as the one from which the zero vector was subtracted.
