Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

One type of ink-jet printer, called an electrostatic
ink-jet printer, forms the letters by using deflecting
electrodes to steer charged ink drops up and down
vertically as the ink jet sweeps horizontally across
the page. The ink jet forms 35.0 μm-diameter
drops of ink, charges them by spraying 800,000
electrons on the surface, and shoots them toward
the page with a horizontal velocity of 17.0 m/s.
Along the way, the drops pass through the long axis
of two horizontal, parallel electrodes that are
6.0 mm long, 4.0 mm wide, and spaced 1.0 mm
apart. The distance from the center of the
electrodes to the paper is 1.90 cm. To form the
letters, which have a maximum height of 6.0 mm,
the drops need to be deflected up or down a
maximum of 3.0 mm. Ink, which consists of dye
particles suspended in alcohol, has a density of
800 kg/m³.
