HELP!! An illustration of a pendulum at 3 positions of a pendulum. The equilibrium position is labeled B. The other two position
s are the maximum displacement of the pendulum labeled A and C. In between A and B are 3 lighter colored pendulum sketches equally spaced. In between B and C are 3 lighter colored pendulum sketches equally spaced.
At which point(s) does the pendulum have the greatest potential energy?
A only
B only
C only
both A and C

Answer:
84.82N/C.
Explanation:
The x-components of the electric field cancel; therefore, we only care about the y-components.
The y-component of the differential electric field at the center is
.
Now, let us call the charge per unit length, then we know that
;
therefore,
Integrating
Now, we know that
and the radius of the semicircle is
therefore,
