Suppose i have a uniformly charged spherical shell with charge density sigma. i place a point charge inside the shell, slightly off center. which of the following statements is true? the particle will feel zero net force. the particle will feel a non-zero net force towards the center point the particle will feel a non-zero net force away from the center point [2 points] a point charge (charge = 10 mc, mass = 3 g) is accelerated through a potential difference of 300 volts. what is the magnitude of the change in kinetic energy of the particle? j [2 points] a region of space has an electric potential equal to v(x) = 3 x2. what is the magnitude of the electric field at the point x=1? n/c [2 points] which of the following statements is not true? the electron-volt is a unit of energy electric potential is a vector quantity electric potential energy is a scalar quantity the si unit for electric potential is the volt the electric field points in the direction in which the electric potential decreases most rapidly [2 points] true or false? if the electric potential at a certain point in space is zero, then the electric field at that same point in space is also zero. true false
