2 m ऊंचाई का आदमी 6 m ऊंचे बिजली के खंभे से दूर 5 km/h की समान चाल से चलता है| उसकी छाया की लमबायी की वृद्धि की दर ज्ञात कीजिए |

Explanation

To solve the problem, we will use the concept of similar triangles and related rates. Let's break it down step by step.

### Step 1: Understand the problem
We have a man who is 2 meters tall walking away from a 6-meter tall electric pole. We need to find the rate at which the length of his shadow is increasing as he walks away from the pole at a speed of 5 km/h.

### Step 2: Set up the diagram
1. Let \( AB \) be the height of the pole (6 m).
2. Let \( CD \) be the height of the man (2 m).
