A small white object began to slowly emerge from beneath the sleeve of Mr. H's sweater. It took several laughs and giggles from the class before the emerging sheet of fabric softener caught Mr. H's attention. He turned the potentially embarrassing moment into a serendipitous moment. Pulling the sheet out from beneath the sweater, Mr. H wrote the following problem on the board. A sheet of cationic fabric softener having a surface charge of 3.6x10-12 C (positive) clings to a wool sweater with a negative charge of 6.8x10-9 C. Determine the force of electrical attraction if they can be treated as point objects with a separation distance of 0.019 cm. What is the answer to this problem?

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
