A cavity of radius r is made inside a solid sphere. The volume charge density of the remaining sphere is ρ. An electron (charge e, mass m) is released inside the cavity from point P as shown in figure. The centre of sphere and centre of cavity are separated by a distance a. The time after which the electron again touches the sphere is

An infinite nonconducting sheet has surface charge density s. There is a small hole in the sheet as shown in the figure. A uniform rod of length l having linear charge density λ is hinged in the hole as shown. If the mass of the rod is m, then the time period of oscillation for small angular displacement is
