Question
The information below and the next 4 problems apply to one complete problem which is broken up into parts as discussed in the class.A thin glass rod bent in a semi-circular shape symmetric about the x-axis. (See Fig. 2.) The quarter circle section above the x axis has a charge of +15.4 micro-Coulomb and the bottom section has a charge of -15.4 micro-Coulomb. The radius of the semi-circular section is is 3.80 cm. You will determine the electric field at the center P by doing the next set of problems. This gives practice in using the steps to solve this type of problem.
The charge density of the upper quarter circle is ____________. Give your answer in the form "+/-a.bc x 10^(y)" C/m. (Do you agree that the SI unit is C/m? Be sure that you understand that this unit is correct!)
The charge density of the lower quarter circle is ____________. Give your answer in the form "+/-a.bc x 10^(y)" C/m.
Explanation / Answer
a.bc x 10^(y) a=2 b=3 c=1 y=9 b)with -ve sign a=2 b=3 c=1 y=9 only the sign differs
