An object has a charge of -3.8 µC. How many electrons must be removed so that the charge becomes +4.0 μC? Number i Units ✪

A charge of 7.65 mCmC is placed at each corner of a square 0.240 mm on a side. Determine the magnitude of the force on each charge. Determine the direction of the force on a charge.

A charged wire with a charge density of A=1.2 µC / m is bend into the shape of a ring with a radius of 0.2 m. Determine the total charge of the ring in units of µC using one decimal point.

A net charge of 39 mC passes through the cross-sectional area of a wire in 22 s. HOw many electrons pass the cross sectional area in 4.0 min?

How many electrons make up a charge of -50.0 μC ? Express your answer using three significant figures.

A +4.23 μC charge lies 0.002 m to the left of a - 5.79 µC charge. A - 9.23 µC charge lies 6.5 m to its right. What is the magnitude? Answer:

Consider the following. 60.0⁰ 0.500 mm (a) Red blood cells often become charged and can be treated as point charges. Healthy red blood cells are negatively charged, but unhealthy cells (due to the presence of a bacteria, for example) can become positively charged. In the figure, three red blood cells are oriented such that they are located on the corners of an equilateral triangle. The red blood cell charges are A = 1.80 pC, B = 7.10 pC, and C = -4.80 pC. Given these charges, what would the magnitude and direction of the electric field be at cell A? (1 pC = 1 x 10-12 C.) magnitude N/C direction counterclockwise from the +x-axis (b) If the charge of cell A were doubled, how would the electric field at cell A change? O The field would be unchanged. O The magnitude of the field would be doubled. O The magnitude of the field would be halved. O The magnitude of the field would be quadrupled.

Most workers in nanotechnology are actively monitored for excess static charge buildup. The human body acts like an insulator as one walks across a carpet, collecting -50 nC per step. What charge buildup will a worker in a manufacturing plant accumulate if she walks 25 steps.  How many electrons are present in that amount of charge?
