### Problem Statement

A solid cylindrical object made of copper (Cu) has the dimensions as shown in the figure. Given the conductivity of Cu \(\sigma_{Cu} = 5.8 \times 10^7\) (S/m).

- **Cylinder Dimensions:**
  - Length (\(l\)) = 10 cm
  - Radius (\(r\)) = 1 cm

Calculate the resistance between two opposite circular surfaces.

### Answer Options

- ○ None of these
- ○ \(5.49 \, n\Omega\)
- ○ \(10 \, \mu\Omega\)
- ○ \(10 \, \Omega\)
- ○ \(5.49 \, \mu\Omega\)

### Diagram Explanation

The diagram presents a cylindrical object, with its radius labeled as 1 cm and length as 10 cm. This diagram serves as a visual representation to assist with the calculation of electrical resistance between the circular surfaces of the cylinder given its conductivity.
