Two guys who weight the same are holding onto a massless pole while standing on horizontal frictionless ice.
1)If the guy on the left starts to pull on the pole, where do they meet?

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply.the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
