Question

A ring shaped tube contain two ideal gases with equal masses and relative molar masses `M_1=32 and M_2=28.`
The gases are separated by one fixed partiotin and another movable stopper S which can move freely without friction inside the ring. The angle `alpha` as shown in the figure is ...... degrees.

A. 291
B. 219
C. 129
D. 192

Answer 1

Correct Answer - D
Pressure on both sides should be same or,
`(n_(r)RT)/(V_(1))=(n_(2)RT)/(V_(2))orm/(32(360^(@)-alpha))=m/(28 alpha)`
or `" "alpha=192^(@)`
