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.)

Ibelieve the answer is b

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
