Here is my problem: A 2.50g particle moves in a circle of radius 3.00m. The magnitude of its angular momentum relative to the center of the circle depends on time according to L = (3.5 Nm)t. Find the magnitude of the torque acting on the particle. I know that: T = F L where T = torque F is the force L is angular momentum I feel like this problem is more algebraic than anything. I just need something stable to start from. Pleeeeeeeeaaaase Heeeeeeelp!!
