Question

Consider the diagram given below, the maximum compression in the spring will be, all the surfaces are smooth and F1>F2

1)( F1 - F2)/2K

2) (F1+F2)/2K

3) F1/K

4) F2/K

Answer 1

Find the position of centre of mass

Separate the spring in two halves from centre of mass

Think about spring constant of each separated spring

Then find expansion or compression on each spring

Then find the net compression or expansion
