Question: a dust particle has an excess charge of 30106electrons and...

Question details

A dust particle has an excess charge of 3.0×106electrons and a mass of 4.0×10−8g. It is initially held at d=1.0×10−3m directly above a fixed object of the same size that is charged with the same number of electrons. Both objects are in an evacuated container.

Part A: Determine the maximum height of the dust particle after its release measured from its initial position.

Part B:

What quantities can be determined using the given data?

Check all that apply.
