the two halves of the rod in the figure are uniformly charged to ±q. (figure 1)

The two halves of the rod in the figure are uniformly charged to plus/minus Q as shown.

What is the electric potential at the point indicated by the dot?

Solutions

Expert Solution

Given that, the two halves of the rod in the figure are uniformly charged

to plus and minus charge. Since the rod is uniformly charged, the potental

due to first half of the rod is equal to the potential due to second half of the

rod, but both have opposite signs. So, the two potentials will cancel each

other. Hence, the electric potential at the point indicated by the dot is zero,

that is, \(V_{\text {ret }}=0\)
