An object with a charge of -3.1\mu C and a mass of 1.0*10^-2 kg experiences an upward electric force, due to a uniform electric field, equal in magnitude to its weight. Find the magnitude of the electric field. Find the direction of the electric field If the electric charge on the object is doubled while its mass remains the same, find the direction and magnitude of its acceleration. If the electric charge on the object is doubled while its mass remains the same, find the direction and magnitude of its acceleration.

Using the given data table, calculate the acceleration of the skateboarder. you can use either form of the equation below?

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
