A charged particle q is thrown with a velocity v towards another charged particle Q at rest. It approaches Q up to a closest distance r and then returns. If q is thrown with a velocity 2v, what should be the closest distance of approach?

An another point charge q, thrown towards the stationary point charge Q at speed v, it returns at a distance r from Q. If 2v speed is given instead of v then distance of closest approach will be ………

A particle of mass m, charge q gt 0 and initial kinetic energy K is projected from infinity towards a heavy nucleus of charge Q assumed to have a fixed position. (a) If the aim is perfect, how close to the centre of the nucleus is the particle when it comes instantaneously to rest ? (b) With a particular imperfect aim, the particle's closest approach to nucleus is twicw the distance determined in (a). Determine speed of particle at the closest distance of approach.

A long straight wire carries a current i. A particle having a positive charge q and mass m, kept at distance x_0 from the wire is projected towards it with speed v. Find the closest distance of approach of charged particle to the wire.
