A particle moves in a circle of radius 4 m. Its linear speed is given by 4√3 t, where t is the time measured in seconds. At t = 1 s, the angle made by the resultant acceleration – r̂ with direction (+ r̂ is the radial direction) is given by φ. Which one among the following is the correct value of φ ?
tan⁻¹ (1/√3)
tan⁻¹ (1/√2)
tan⁻¹ (2/√3)
tan⁻¹ (√3)
