An ion source is producing 6 Li ions, each of which has a charge e and a mass of 9.99 x 10-27 kg. After being accelerated by an electric potential difference of 644 kV, the ions pass into a region containing both uniform electric and magnetic fields. If the magnetic field has a magnitude of 0.199 T and is oriented vertically, what is the magnitude of the smallest electric field that would allow the ions to pass through the region undeflected

"induction" is the process of charging an object without touching it.hope my answer has you : )

Answer: 1.4 seconds which is the third optionexplanation: current is defined as the flow of charge per timetherefore, the equation that relates current, charge and time can be expressed as follows: i = δq / δtwhere: i is the current given = 1.8 ampereδq is the charge given = 2.5 coulombδt is the time required for the flow of the given charges to give the 1.8 ampere.substitute with the givens in the above equation to get the time as follows: 1.8 = 2.5 / δtδt = 2.5 / 1.8 = 1.38888 which is approximately 1.4 secondshope this was !
