Full Marks : +3 If ONLY the correct option is chosen;
Zero Marks : 0 If none of the options is chosen (i.e. the question is unanswered);
Negative Marks : -1 In all other cases
If the distribution of molecular speeds of a gas is as per the figure shown below, then the ratio of the most probable, the average, and the root mean square speeds, respectively, is
Text Solution
Verified by ExpertsB
Since the graph is symmetrical about the peak. So, the average speed and most probable speed will coincide but rms speed will remain , 
So, 
=1:1:1.224
