Answer» Here, V_d = a * τ a - acceleration = Ee / m And τ = relaxation time Second one is very interesting one We know I = n * A * V_d * e Mutiply on R H S by L both nr and dr So I = n * v * V_d * e / L (v - volume which remains constant) But I = E/R Now E/R = n * v * V_d * e / L We know that R is proportional to L² provided volume remains constant Now dropping all non changing quantities we have 1/R is proportional to V_d / L OR V_d is proportional to L/R You are increasing the length 3 times and resistance increases by 9 times Hence new V_d = 3/9 = 1/3 of the original Drift velocity is reduced to one-third of its original value

32.

Find the relation between drift velocity and relaxation time of charge carriers in a conductor. (b) A conductor of length

Answer»

Here, V_d = a * τ

a - acceleration = Ee / m

And τ = relaxation time

Second one is very interesting one

We know I = n * A * V_d * e

Mutiply on R H S by L both nr and dr

So I = n * v * V_d * e / L (v - volume which remains constant)

But I = E/R

Now E/R = n * v * V_d * e / L

We know that R is proportional to L² provided volume remains constant Now dropping all non changing quantities we have 1/R is proportional to V_d / L

OR V_d is proportional to L/R You are increasing the length 3 times and resistance increases by 9 times

Hence new V_d = 3/9 = 1/3 of the original

Drift velocity is reduced to one-third of its original value

46.	How would you distinguish experimentally between an alcohol and a carboxylic acid?
Answer» Sodium bicarbonate test is the best method to experimentally distinguish carboxylic acid from alcohol because even phenol does not respond to this test. In this test, carboxylic acid reacts with sodium bicarbonate to form sodium acetate and a brisk effervescence of CO₂. This effervescence is what indicates the carboxylic acid. RCOOH + NaHCO₃ → RCOONa + H₂O + CO₂ NOTE: Sodium bicarbonate test is also known as sodium hydrogen-carbonate test.
