When an object such as a plastic comb is charged by rubbing it with a cloth, the net charge is typically a few microcoulombs. If that charge is 3.9 μC , by what percentage does the mass of a 30 g comb change during charging? Express your answer using two significant figures.

when an object such as plastic comb is charged by rubbing it with a cloth, the net charge is typically a few microcoulombs. if that charge is 3.0 uC. a- what percentage does the mass of a 9.0 g comb change during charging? b- If these were charges on a rubber ball, would you be able to hold these balls apart? c- What does this tell you about the likelihood of finding these size charges on ordinary objects?
After charging the plastic rod negatively by rubbing with the fur, bring it near to (but not touching) the proof plane and keep it there for a second. Then, while keeping the plastic rod near (but not touching) the proof plane, move the proof plane away from the grounded object. Once contact between the proof plane and the bar is broken, the rod is moved away. How does the proof plane acquire charge without touching the charged rod?
Question 10 of 10> A large positively charged object with charge q+-4.25 μC is brought near a negatively charged plastic ball suspended from a string of negligible mass. The suspended ball has a charge of q-47.3 nC and a mass of 12.5 g. What is the angle the string makes with the vertical when the positively charged object is 18.5 cm from the suspended ball? The positively charged object is at the same height as the angle 26
A large positively charged object with charge q + = 3.75 μC is brought near a negatively charged plastic ball suspended from a string of negligible mass. The suspended ball has a charge of q − = − 53.3 nC and a mass of 12.5 g. What is the angle the string makes with the vertical when the positively charged object is 22.5 cm from the suspended ball? The positively charged object is at the same height as the suspended...
