Question

A highly rigid cubical block A of small
mass M and side L is fixed rigidly onto
another cubical block B of the same
dimensions and of low modulus of
rigidity n such that the lower face of A
completely covers the upper face of B.
The lower face of B is rigidly held on a
horizontal surface. A small force Fis
applied perpendicular to one of the side
faces of A. After the force is withdrawn,
block A executes small oscillations, the
time period of which is given by​
