Two masses MAM_A and MBM_B are hung from two strings of length lAl_A and lBl_B respectively. They are executing SHM with frequency relation fA=2fBf_A=2f_B, then relation

Multiple Choice Options

  • A lA=lB4l_A=\frac{l_B}{4} does not depend on mass
  • B lA=4lBl_A=4l_B, does not depend on mass
  • C lA=2lBl_A=2l_B and MA=2MBM_A=2M_B
  • D lA=lB2l_A=\frac{l_B}{2} and MA=MB2M_A=\frac{M_B}{2}.

Step-by-Step Verified Solution

f A = 2 f B _ 1 2 � g l A = 2 _ 1 2 � g l B _ l l A = 4 _ l l B _ l A = l B 4 , which does not depend on mass.
