An object weighing 4 newtons swings on the end of a string as a simple pendulum. At the bottom of the swing, the tension in the string is 6 newtons. What is the magnitude of the centripetal acceleration (in m/s²) of the object at the bottom of the swing? (consider the magnitude of gravitational acceleration is g m/s²).
