A certain lightning bolt moves 39.4 C of charge. How many fundamental units of charge |qe| is this? × units of charge 19el

An object has a charge of 35 nC. How many excess protons does it have?

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.

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.
