T he acceleration of free fall is g current at which 25 A thin uniform conducting disc of radius r and mass m rests on a horizontal tabletop where a uniform magnetic field of induction B pointing vertically upwards exists Coefficient of friction between the disc and the tabletop is u Two points P and P2 on the rim of the disc are connected with two flexible wires which facilitate a current to flow through the disc The contact points P and P2 subtend an angle at the centre of the disc How much minimum current must flow through the disc so that it begins to slide Acceleration of free fall is g A conducting fluid of maca dons poristivity fe is kept O B I O P O O O O O O Pz 1 O O 7 O O O
