Question number: 1
» Special Relativity, Waves & Geometrical Optics » Waves » Damped Oscillation
Appeared in Year: 2013
Write in Short
A block of mass is attached to one end of a combination of two massless springs connected in series. The other end of the combination is fixed to a rigid support. The spring constatnts of the two springs are and , respectively. The block is free to move on a frictionless horizontal surface. If the block is pulled a little and then released, calculate the frequency of oscillation of the block. (Section A)

Appeared in Year: 2013
Describe in Detail
A block of mass is attached to one end of a combination of two massless spring connected in series. The other end of the combination is fixed to a rigid support. The spring constant of the two spring are and , respectively. The block is free to move on a frictionless horizontal surface. If the block is pulled a little and then released, calculate the frequency of oscillation of the block.
Explanation
Series Combination of Springs
In figure a series combination of the springs are shown. One end is connected with a block of mass m.
