Physics · JEE | MOTION IN A PLANE

For an object moving in a plane with velocity components \( v_x \) and \( v_y \), the direction angle \( \theta \) of the velocity vector with the \( x\text{-axis} \) is given by:

1. A
   \( \theta = \sin^{-1}(\frac{v_x}{v_y}) \)
2. B
   \( \theta = \tan^{-1}(\frac{v_x}{v_y}) \)
3. C
   \( \theta = \tan^{-1}(\frac{v_y}{v_x}) \)
4. D
   \( \theta = \cos^{-1}(\frac{v_y}{v_x}) \)
