In activity shown,how do you think the displacKHOent of rod AB will be affected :Length of the rod AB is increased

In activity shown,how do you think the displacKHOent of rod AB will be affected :if the current in rod ab is increased,

In activity shown,how do you think the displacKHOent of rod AB will be affected :A stronger horse shoe magnet is used,

In figure, how do we think the displacement of rod AB will be affected if (i) current in the rod AB is increased, (ii) a stronger horse-shoe magnet is used, and (iii) length of the rod AB is increased?

A small aluminium rod AB is suspended horizontally from a stand by the ends of two connecting wires as shown in the Figure given here. A horseshoe magnet is placed in such a way that north pole of the magnet is vertically below and its south pole vertically above the aluminium rod. The aluminium rod is connected in series with a battery, a key and a rheostat. How do you think the displacement of rod AB will be affected if : (i) current in rod AB is increased ? (ii) a stronger horseshoe magnet is used ? (iii) length of the rod AB is increased ?

End A of a rod AB is being pulled on the floor with a constant velocity v_(0) as shown. Taking the length of the rod as l , at an instant when the rod makes an angle 37^@ with the horizontal, calculate the velocity of the CM of the rod
