The electric potential of a volume of space is defined by v v(x, y, z)=x'yz + xz -y, where is x, y, andz are in meters, then the potential is in volts. a) what is the voltage from (1, 2, 3) to (4, 3, 2)? (all positions b) find another point which shares an equipotential line with (1, 2, 3) c) what is the formula for the electric field, e? a particle is placed at (1, 2, 3) and it moves to (4, 3, 2) d) is the particle more likely an electron or a proton? why? are in meters.)
