A typical lightning flash delivers about 25 C of negative charge from cloud to ground. How many electrons are involved?
Find the magnitude of the electric force on a 2.0 - \(\mu \mathrm{C}\) charge in a \(100-\mathrm{N} / \mathrm{C}\) electric field.
A \(9.5-\mu \mathrm{C}\) charge is at \(x=15 \mathrm{cm}, y=5.0 \mathrm{cm}\) and a \(-3.2-\mu \mathrm{C}\) charge is at \(x=4.4 \mathrm{cm}, y=11 \mathrm{cm} .\) Find the force on the negative charge.
You're \(1.44 \mathrm{m}\) from a charge distribution that is well under \(1 \mathrm{cm}\) in size. You measure an electric field strength of \(296 \mathrm{N} / \mathrm{C}\) due to this distribution. You then move to a distance of \(2.16 \mathrm{m}\) from the distribution, where you measure a field strength of \(87.7 \mathrm{N} / \mathrm{C}\) What's the net charge of the distribution? Hint: Don't try to calculate the charge. Determine instead how the field decreases with distance, and from that infer the charge.
A \(65-\mu \mathrm{C}\) point charge is at the origin. Find the electric field at the points (a) \(x=50 \mathrm{cm}, y=0 \mathrm{cm} ;\) (b) \(x=50 \mathrm{cm}, y=50 \mathrm{cm}\) and \((\mathrm{c}) x=25 \mathrm{cm}, y=-75 \mathrm{cm}\)
