## What angle magnitude of cross product and dot product of two vectors are equal?

Ans: When angle between two vectors is 45 degree, cross product and dot product of two vectors are equal.

Is magnitude of cross product equal to dot product?

Cross product will results in a vector, with a magnitude and direction – even if the magnitude may be 0, and dot product will results in a scalar. Adding to that, the magnitude of the cross product can be the same as the result of the dot product when , assuming that is the angle between the two operand vectors.

### What does it mean when the dot product equals the cross product?

A dot product is the product of the magnitude of the vectors and the cos of the angle between them. A cross product is the product of the magnitude of the vectors and the sine of the angle that they subtend on each other. The dot product is zero when the vectors are orthogonal ( θ = 90°).

How is the magnitude of the cross product of two vectors related to the magnitude of the individual vectors and the angle between them?

The equation to calculate a cross product is pretty simple. The cross product between vectors A and B is equal to the magnitude of vector A multiplied by the magnitude of vector B multiplied by sine of the angle between them. That will give you the magnitude of your answer.

## What is the cross product of two equal vectors?

When two vectors are multiplied with each other and the product of the vectors is also a vector quantity, then the resultant vector is called the cross product of two vectors or the vector product. The resultant vector is perpendicular to the plane containing the two given vectors.

What is the magnitude of a cross product?

The magnitude of the resulting vector from a cross product is equal to the product of the magnitudes of the two vectors and the sine of the angle between them.

### What is the dot product of two cross products?

Given two unit vectors, their cross product has a magnitude of 1 if the two are perpendicular and a magnitude of zero if the two are parallel. The dot product of two unit vectors behaves just oppositely: it is zero when the unit vectors are perpendicular and 1 if the unit vectors are parallel.

How do you find the magnitude of the cross product of two magnitudes?

## Can cross product and dot product of two vectors be the same?

Dot product and Cross product of two vectors cannot be same because resultant of dot product is a scalar quantity and that of vector product is a vector. What should be the angle between two vectors of equal magnitude so that the magnitude of the resultant is equal to the magnitude of two vectors? The required angle is 120 degree.

What is the ratio of the magnitude of Cross and dot products?

Using the known formulas for dot and cross product relating the magnitudes and the angle we get for vectors a,b The ratio of the magnitude of cross and dot products of two vectors is tan θ . If they were equal , then tan θ = 1 which implies θ = 45 degree.

### How do you find the angle between two vectors using cross product?

Angle Between Two Vectors Using Cross Product. The formula of the angle between two vectors using the cross product is as follows: a → × b → = | a → | | b → | s i n θ n ^. , where, n ^. denotes the unit vector that shows the direction of the multiplication of two vectors.

What is the difference between dot product and cos product?

Both the definitions are equivalent when working with Cartesian coordinates. However, the dot product of two vectors is the product of the magnitude of the two vectors and the cos of the angle between them. To recall, vectors are multiplied using two methods
