Question

A long thick solid conductor has a cylindrical cavity of radius $$1$$ m parallel to its axis at a distance of $$2m$$ from centre of cylinder. Cylinder have uniform  surface current density  $$J=106$$$$π$$$$A/m2k^$$  A charged particle of mass  $$0.1$$ kg and charge  π coulomb is projected with velocity v at an angle of $$60$$º as shown in figure.  For what maximum v, particle is able to  strike point B?

Infinity Learn · Accepted Answer

B inside the cavity is given as  μ$$02j$$→×a→$$=0.4j^Inside$$ the cavity particle will undergo  helical path $$P=Vcos$$θ×$$2$$$$π$$mqB
