A) \[{{30}^{\text{o}}}\]
B) \[{{45}^{\text{o}}}\]
C) \[{{60}^{\text{o}}}\]
D) \[{{0}^{\text{o}}}\]
Correct Answer: C
Solution :
Draw the situation as shown. OA represents the path of the particle starting from origin O(0, 0). Draw a perpendicular from point A to x-axis. Let path of the particle makes an angle \[\Omega \] with the x-axis, then \[\phi \] = slope of line OA \[\phi ={{\phi }_{0}}+4t\] or \[\phi \]You need to login to perform this action.
