| LIST-I (Configuration of Bipolar Transistors) | LIST-II (Characteristics) | ||
|---|---|---|---|
| A. | Common Base | I. | Current Gain but no Voltage Gain |
| B. | Common Emitter | III. | Both Current and Voltage Gain |
| C. | Common Collector | II. | Voltage Gain but no Current Gain |
Choose the correct answer from the options given below:

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
