Suppose you performed the experiment in atmosphere of argon at 25 deg. c, (viscosity of argon is 2.26x10^-5 n. s/m^2 at that temperature), and measured terminal speed of 2.64x10^-5 m/s and weight-neutralizing voltage of 35.0 v. how many electrons have been attached to, or detached from the initially neutral plastic sphere

Ireally don’t know

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
