A wire of mass m and length l is placed on a smooth incline making an angle θ with the horizontal, whose fornt view is shown in Fig. When a finite amount of charge is passed through it in an infinitesimal time, the wire immediately acquires some velocity and then ascends the incline by a distance s. For this small duration, we can neglect the gravitational force because the current can be considered very large due to small time duration. The amount of charge passed through the wire is

A particle of charge q and mass m enters normally (at point P) in a region of magnetic field with speed v. It comes out noramally from Q after time T as shown in Fig. The magnetic field B is present only in the region of radius R and is uniform. Initial and final velocities are along radial direction and they are perpendicular to each other. For this to happen, which of the following expression (s) is are correct?
