1D... ans.
Three identical rings move with the same speed on a horizontal surface in a uniform horizontal mag. field normal to the plane of the rings. The first (A) slips without rolling , the second (B) rolls without slipping , & the third rolls with slipping.
a) The same emf is induced in all the 3 rings
b)No emf is induced in any of them
c)In each ring all points are at same potential
d)B develops the max. emf followed by C and A
mark the correct option,

1because B is moving at the fastest pace,so max change in flux,so max emf
1No.... guys ......D is the answer.....Think....Think....
Gr8 wrk SKY....
21hmmmm!!!!
BUT SKY : if u consider the bottom most point.....
In B : It has zero velocity coz pure roling : wR - wR
so NO EMF!!!!!!!
yah if v consider the Emfs wid direction then ans wud nto change I guess
Wat Say??
21matlab?
if v consider same ω for each n thn c wich has max V , and hence E = BLV aisa kuch?
1oh i didn't check the options correctly in the first place,i meant (D) not (C)
