5 g particle carries a charge of 5.00 uC. - The particle hovers motionless over a conducting plate which which lies on the horizontal. hat is the charge density on the top side of the nducting plate?

A factory is spray-painting large sheets of metal electrostatically.  The sheets have dimensions of 2.4 m by 2.4 m and are charged with 0.82 mC.  A 10 kg drum of paint is charged with -89 μCμC, and the spray nozzle produces uniform droplets of 2.4 g.  Assume that all charge is distributed uniformly on the sheet and in the paint and no charge is lost during the spraying process.  Determine the magnitude of acceleration the paint droplets feel due to the metal sheet.   Give your answer in units of ms2ms2.

An object has a charge of -2.00 pC on it. How many electrons would you have to add/remove to make the charge become -5.00 pC?

QUESTION 19 The initially-neutral, conducting, solid object diagrammed below contains two inner cavities. A point charge, +7Q is then placed in one of the cavities while a point charge of -3Q is placed in the other cavity. (Q > 0) What resultant charge resides on the outer surface of the conductor after the conductor is allowed to reach electrostatic equilibrium? +7Q -3Q а. +4Q b. -3Q Ос. -4 d. +7Q е. -3Q

The net charge generated by a plastic comb rubbing against the fabric is a few micocoloumb (μC). If this load is 3.0 μC, what is the percentage change of mass of a 35 gram comb during this loading?

A particle of mass 5.4×10^−6 g and a charge of −2 nC starts out traveling horizontallyat 500 m/s straight between two oppositely charged plates separated by 3 cm. The plateshave surface charge densities of 9 µC/m^2Determine the following:a) How long till it impacts either plate?b) How far will it travel horizontally until it impacts one of the plates?

5. In below figure, a small, non-conductor ball of mass m =3.0 mg and charge q = 9.0 µC hangs from an insulating thread that makes an angle e charged non- conductor plane. Considering the gravitational force on the ball and assuming the plane extends far vertically and into and out of the page, calculate the area charge density of the plane. Length of string is 120.0 cm. 30° with a vertical, uniformly lo120cm + Jplone

A 0.01294 kg ball with a positive charge of 47.4 μC hangs from a light string right next to a large vertical metal plate (the metal plate is so large compared to the length of the string and ball consider it to be infinite in size).  How much surface charge density must the plate have to repel the ball so that the string makes and angle of 5.03 degrees from the vertical.  Give your answer to 3 significant figures and in units of nC/m/m (nanoCoulombs per meter squared: Blackboard has trouble with squred units).  Type in the units right after your numerical answer.

a point particle with a positive charge q and a mass is held stationary by the forces of gravity ad electricity above an infinitely,thin,plane sheet of positive charge with charge positive density? what is the value of density
