Questions
Two springs are connected to a block of mass M placed on a friction less surface as shown in fig. (1). If both the
springs have a spring constant k, the frequency of oscillation of the block is
detailed solution
Correct option is B
For spring block system, the time period of oscillation is given by T=2πMkeqwhere keq is equivalent spring constant of springs. Here 1keq=1k+1k=2k or keq=k2 T=2πM(k/2)=2π2Mk or n=1T=12πk2MTalk to our academic expert!
