A point charge Q1=−125μC is fixed at the center of an insulated disc of mass 1 kg. The disc rests on a rough horizontal plane. Another charge Q2=125μC is fixed verically above the center of the disc at a height h=1m. After the disc is displaced slightly in the horizontall direction (friction is sufficient to prevent slipping), find the period of oscillation of disc.

A charged particle q of mass m is in wquilibrium at a height h from a horizontal infinite line charge wit uniform linear charge density λ. The charge lies in the vertical plane containing the line charge. If the particle is displaced slightly (vertically) prove that the motion of the charged particle will be simple harmonic. Also find its time period.

A block of mass m1 moves with an acceleration a12 relative to a trolley as shown in figure. The block is being observed by two observers (2) and (3). The observer (2) is at rest with respect to trolley which is moving with acceleration a2 while the observer(3) is moving on ground with acceleration a_3. What is the work done by the pseudo force as observed by the observers (2) and (3) on the block during time t? Assume zero intial velocities of the bodies and observers.
