An equilateral triangular loop 
of uniform specific resistivity having some resistance is pulled with a constant velocity 
out of a uniform magnetic field directed into the paper. At time 
, side 
of the loop is at the edge of the magnetic field. The induced current (I) versus time 
graph will be as:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Let 
be the side of the triangle and 
the length 
.
and 
are similar triangles.
Induced e.m.f., 
∴ Induced current, 
or 
Thus, the 
graph is a straight line with a negative slope and positive intercept.
