A mass is connected by a light string that passes over a pulley of mass M to a mass
as shown in the figure. Both masses move vertically and there is no slippage between the string and the pulley. The pulley has a radius of 20.0 cm and a moment of inertia of 1?2
If
is 3.00 kg,
is 6.00 kg and M is 4.00 kg, then what is the tension in the string that is attached to mass

A parallel plate capacitor is charged to voltage V and then disconnected from the battery. Leopold says that the voltage will decrease if the plates are pulled apart. Gerhardt says that the voltage will remain the same. Which one, if either, is correct, and why?
A. Gerhardt, because the maximum voltage is determined by the battery. B. Gerhardt, because the charge per unit area on the plates does not change. C. Leopold, because charge is transferred from one plate to the other when the plates are separated. D. Leopold, because the force each plate exerts on the other decreases when the plates are pulled apart. E. Neither, because the voltage increases when the plates are pulled apart.
