A uniform magnetic field of 1.5 T exists in a cylinderical region of radius 10.0 cm, its direction being parallel to the axis along east to west. A current carrying wire in north-south direction passes through this region. The wire intersects the axis and experience a force of 1.2N downwards. If the wire is turned from north south to northest-southwest direction. then magnitude and direction of force is

A particle of positive charge q and mass m enters with velocity V j ^at the origin in a magnetic field B(− k ^ ) which is present in the whole space. The charge makes a perfectly inelastic collision with an identical particle (having same charge ) at rest but free to move at its maximum positive y−coordinate. After collision, the combined charge will move on trajectory (where r = qB /mV ) :
