Two masses MA and MB are hung from two strings of length lA and lB respectively. They are executing SHM with frequency relation fA = 2fB, then relation

  1. lA = lB4, does not depend on mass
  2. lA = 4lB, does not depend on mass
  3. lA = 2lB and MA = 2MB
  4. lA = lB2 and MA = MB2

Answer

(1) lA = lB4, does not depend on mass

Solution

For a simple pendulum, f = 12 gl, which does not depend on the mass of the bob.

fAfB = lBlA

2 = lBlA

lA = lB4 (independent of mass)

Answer: (1)
