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.

The repulsion arising from the excess charge prevents the cells from clumping together. One cell carries -3.00 pC and the other -2.60 pC, and each cell can be modeled as a sphere 3.75 × 10-º m in radius.
