A 1.0-μm-diameter oil droplet (density 900 kg/m3) is negatively charged with the addition of 27 extra electrons. It is released from rest 2.0 mm from a very wide plane of positive charge, after which it accelerates toward the plane and collides with a speed of 3.1 m/s .
Part A
What is the surface charge density of the plane?

A microscopic oil droplet containing 1000 electrons is at rest and in equilibrium, floating above a negatively charged disk. What is the surface charge density of the disk? Assume the droplet is very near the surface of the charged disk. (Include the sign of the value in your answer. Assume the mass of the microscopic oil droplet is measured to be 3.5 x 10 1 kg.)

In the early 1900s, Robert Millikan used small charged droplets of oil, suspended in an electric field, to make the first quantitative measurements of the electron’s charge. A 0.74-μm-diameter droplet of oil, having a charge of +e+e, is suspended in midair between two horizontal plates of a parallel-plate capacitor. The upward electric force on the droplet is exactly balanced by the downward force of gravity. The oil has a density of 860 kg/m3, and the capacitor plates are 6.0 mm...

Question 3 A -9.80 nC charge of mass 4.50x10-6 kg is released from rest 1.90 mm above a very large plane of positive charge. The charge accelerates toward the plane and collides with a speed of 1.50 m/s. What is the surface charge density of the plane? O 1.09x10-7 c/m2 3.21x10-6 C/m2 4.81×10-6 C/m2 O 2.41x10-6 C/m2

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 forms33.0 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 23.0 m/s. Along the way, the drops pass through the long axis of two parallel electrodes...

A U-tube contains liquid of unknown density. An oil of density
770 kg/m³ is poured into one arm of the tube until the oil column
is 13.5 cm high. The oil-air interface is then 4.5 cm above the
liquid level in the other arm of the U-tube. Find the density of
the liquid.
