Question:
1) A uranium nucleus has 92 protons. Assume the nucleus to be a point-like object with charge Q = 92e, and ignore interaction with other electrons.
Part A
Determine the magnitude of the E → field at a distance of 6.7×10 −13 m from the nucleus (about the radius of the innermost electron orbit around the nucleus).
Express your answer to two significant figures and include the appropriate units.
Part B
What is the magnitude of the force exerted on an electron by this E → field?
Express your answer to two significant figures and include the appropriate units.
2) Two objects with charges +4.7×10 −9 C and +3.1×10 −9 C are 56 cm from each other.
Part A
At what distance from the first object the E → field due to these two charged objects is zero.
Express your answer to two significant figures and include the appropriate units.
