Expert Solution
Step 1

Hello. Since your question has multiple sub-parts, we will solve the first three sub-parts (a, b, and c) for you. If you want the remaining sub-parts to be solved, then please resubmit the whole question and specify those sub-parts you want us to solve.

 

(a)

 

The linear charge density along the arc can be determined as follows.

λ=qL=qrθ=-328e6.00 cm72°=-328-1.6×10-19 C6.00×10-2 m72°π rad180°=6.96×10-16 C/m
