The figure shows a 2.0-cm diameter roller that turns at 90 rpm. A 4.0-cm wide plastic film is being wrapped onto the roller, and this plastic carries an excess electric charge having a uniform surface charge density of 9.5 nC/cm2 . What is the current of the moving film?
(Figure 1) shows five electric charges. Four charges with the magnitude of the charge 2.0 nC form a square with the size α = 4.0 cm. Positive charge with the magnitude of q = 1.5 nC is placed in the center of the square.Part A What is the magnitude of the force on the 1.5 nC charge in the middle of the figure due to the four other charges? Part B What is the direction of the force on the 1.5 nC charge...
