6 A 4 kg block with a 50 uc charge is attached to an unstretched spring (k = 100 N/m), on a frictionless
surface
If an electric field of 50000 N/C is suddenly applied to
the right, what will be the initial acceleration of the
block? (3 pts)
a
b.
What type of motion does the block experience? Please
explain. [2 pts)
хео
c
Now, instead, consider the case where the same electric field is turned on, but grows slowly from
O to full strength, what will be the final stretch of the spring from equilibrium? (3 pts)

I give up. What does the back of the book say?

To answer seriously, one must first has to tackle the questions:
What is "2"? and What is "+"?
There is a marvelous little book by Landau (see the sources), usually recommended for advanced math students beginning university, which addresses those questions. It doesn't get as far as actually answering what does 2+2 equal, but sets up the reader to be able to answer such a question properly.
I seem to remember a story about a school with an inscription over the entrance which implies that their graduates should be able to properly answer this question. However I cannot find a reference. Perhaps I should pose that as a question for the Yahoo community ...
