SUMMARY
The net torque on a wheel with dimensions a = 7.00 cm and b = 20.00 cm, assuming a counterclockwise positive direction, is calculated using the formula torque = force x distance. The calculations provided indicate that the net torque is -2.96 Nm, confirming that the 12 N force acts tangentially to the circle of radius a. The 30-degree angle mentioned in the discussion does not affect the tangential force but may cause confusion in understanding the torque calculation.
