Transcribed Image Text:
A total charge Q (coulombs) is uniformly distributed around a ring-shaped conductor with radius a (meters). A smaller point charge q (coulombs) is located at some distance x (meters) from the center of the ring:
a
O
9
The force exerted on the point charge q by the distributed charge Q is given by:
F= 1
qQx
4лe (x² + a²)³/2
where e = 8.9e-12 C2 and F = 2 N. You are asked to choose values for Q.q, and x which satisfy these design requirements:
Nm²
Requirement 1: 3.5≤x≤5 m
•
Requirement 2: 2e-5sq54e-SC
■ Requirement 3:= 10
9
Once you've selected valid parameters, compute a using fzero(). No plotting is required (although you should).
NOTE: There are infinitely many correct answers. There are also infinitely many incorrect answers. Picking random parameter values is a poor strategy; instead, try to find some relationship between them.
