If there is no field inside the conductor, how can there be electric potential?
I think of potential very similar to gravity, as how much energy would be required to move a particle of mass/charge against the gravitational/electric field.
If there is no field at all, how would there still be...
Let the left string be T1 and the right string be T2. Pretend that the masses are NOT equal and that the total mass on the left is 3mg and the total mass on the right is 2mg.
My first thought: Net torque = 3mgR1-2mgR1
Actual solution: Net torque = (T1-T2)*R
Once again, the force that's used...
Why is (1/2)(mv0)^2 = 1/2(M+m0)gh not a valid equation for conservation of energy?
Isn't the energy from when the dart is shot the same as when the two masses move at speed v?
