Question

The scalar product of two vectors 2N,4N is 4 angle between them

Answer 1

60°

Step-by-step explanation:

The scalar product of two vectors with an angle ∅ between them is defined as:

`\overrightarrow{a}\cdot \overrightarrow{b}=|a||b|cos\phi`

Solving for angle ∅:

`\phi= cos^(-1)(\frac{\overrightarrow{a}\cdot \overrightarrow{b}}a)=cos^(-1)((4)/(8))`
