A proton is fired from far away toward the nucleus of an iron atom. Iron is element number , and the diameter of the nucleus is . What initial speed does the proton need to just reach the surface of the nucleus? Assume the nucleus remains at rest.
Two positive point charges q are located on the y-axis at.
a.Find an expression for the potential along the x-axis.
b.Draw a graph of V versus x for . For comparison, use a dotted line to show the potential of a point charge 2qlocated at the origin.
Two 2.0 g plastic buttons each with +50 nC of charge are placed on a frictionless surface 2.0 cm (measured between centers) on either side of a 5.0 g button charged to +250 nC.
All three are released simultaneously.
a. How many interactions are there that have a potential energy?
b. What is the final speed of each button?
An electron with an initial speed of is brought to rest by an electric field.
