Tiny dust particles are attracted to static charges, so if you could get them from the motor to the air intake by the floor, it may help to pick up even more dust. What could you do to get the static from the motor to the floor attachment? Explain your reasoning.

Expert Solution

When an excess of either positive or

negative charge is confined into a relatively small volume (far from any excess charge of the opposite polarity) mutual repulsion

occurs between the charges within that

volume.

This repulsion causes the charges to try to

leave the confining volume and fly apart,

releasing energy. This energy is available

to do damage by sparking.

If two neutral

but dissimilar materials are rubbed

together, causing one to become + and the

other -, there will be very little repulsion

energy available on either object while they are close together. Only when they are

separated will a significant of “spark”

energy be stored on each object. In addition to sparking, charged objects may be

attracted to each other (or repelled). There

is always an attractive force between

uncharged conductors (such as sheet metal or even individual dust particles) and

charged objects (such as an insulating

surface that has just had adhesive removed from it).

Hope this helps.Thanks.

1. 3N Nano-manufacturing purchases Anti-Static Dust-Free suits from a variety of suppliers. However, they have noticed that too many of their products must be discarded due to contamination from defective protective suits. Discarding a finished product costs much more than the suits. a. A close inspection of the suits before use would eliminate almost all defective suits, and contaminated products, but would add some costs. What problems might emerge if 3N offered to pay a premium to suppliers to inspect...
