The mass 
shown in the figure oscillates in simple harmonic motion with amplitude 
.
The amplitude of point 
is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Here the two springs are in series. Let the mass 
be pulled through small distance 
towards right hand side. Due to it, let 
and 
be the extension in two springs. When two springs are in series, the tension or the force is same for both the springs, So 
or 
Total extension, 
;
Amplitude of point 
extension of spring
