For the vector A making an angle with the negative X-axis and lying in the third quadrant, the standard resolved form is
Options
- A-A , i + A , j
- B-A , i - A , j
- CA , i - A , j
- DA , i + A , j
Correct answer
B. -A , i - A , j
Step-by-step solution
The vector A lies in the third quadrant and makes an angle with the negative X-axis. The component of the vector along the negative X-axis is A , so A_x = -A . The component of the vector along the negative Y-axis is A , so A_y = -A . Therefore, the vector in standard resolved form is A = -A , i - A , j . Answer: -A , i - A , j
