We’ve seen that bees develop a positive charge as they fly through the air. When a bee lands on a flower, charge is transferred, and future bee visitors to the same flower can sense this charge and seek out a more promising bloom. Experimenters have done tests to determine the limits of bumblebee field sensitivity. In one test, bumblebees could detect, from a distance, the charge on a 3.0-cm-diameter sphere that had been charged to 30 V. What was the magnitude of the charge on the sphere?

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.
