Q
Q: If the position vector of point P is given by r = 2i + 3j + 4k, what is the x-component of r?
Solution:
The x-component of r is 2.
Steps: 5
Show Steps
Step 1: Understand that the position vector r is written in the form r = xi + yj + zk.
Step 2: Identify the components of the vector r. Here, r = 2i + 3j + 4k.
Step 3: Look for the x-component in the vector. The x-component is the number in front of 'i'.
Step 4: In this case, the number in front of 'i' is 2.
Step 5: Conclude that the x-component of r is 2.
