Answer:

Explanation:
As we know that the charge per unit length of the long cylinder is given as

here we know that the electric field between two cylinders is given by

now we know that electric potential and electric field is related to each other as





B. Flipped compared to what is in the sky
Answer:
22 N applied force
Explanation: Since they are both pushing the wagon in the same direction the force adds up.
