Several positive and negative singly charged ions are accelerated from rest by applying a potential difference of AV before entering a uniform magnetic field B (out of the screen) as shown. L and R represent two fluorescent plates that record the location of a charged particle when it hits a plate. When a singly charged ion q with a mass of ,32 x 10-26 ka is accelerated from rest by a potential difference of 2.50 kV enters the uniform magnetic field, it hits the fluorescent plate K at point P, a distance d of 2.24 cm from its initial position of entrance to the magnetic field. What is the sign of the ion's charge and the strength of the magnetic field? O B AV OAq is negative and magnetic field is 32.4 mT O B. None of the given options Ocq is negative and magnetic field is 2.40 T O D.q is positive and magnetic field is 32.4 mT O E g is positive and magnetic field is 2.40 T
