A rectangular block has dimensions 5 cm `xx ` 5 cm `xx 10 cm ` . Calculate the resistance measured between (a) two square ends and (b) the opposite rectanglar ends specific resistance of the material is `3.5xx10^(-5)` `Omega` m

Explanation

To solve the problem, we need to calculate the resistance of a rectangular block with given dimensions and specific resistance. The dimensions of the block are 5 cm x 5 cm x 10 cm, and the specific resistance (resistivity) of the material is \(3.5 \times 10^{-5} \, \Omega \, \text{m}\).

### Step-by-Step Solution:

**(a) Resistance between the two square ends:**

1. **Identify the dimensions:**
- The square ends are the two faces with dimensions 5 cm x 5 cm.
