A U shaped wire of mass m and length is immersed with its two ends in mercury see figure The wire is in a homogeneous field of magnetic induction B If a charge that is a current pulse q fidt is sent through the wire the wire will jump up Calculate the height h that the wire reaches the size of the charge or current pulse assuming that the time of the current pulse is very small in comparision with the time of flight Make use of the fact that impulse of force equals fFdt which equals mv Evaluate q for B 0 1 Wb m m 10gm l 20cm h 3 meters g 10 m s X X X Hg X X X B X X X X X X ons foting X X X X X X X X m
