As it passes the origin, what are the strength and direction of the magnetic field at the (1 cmcm, 0 cmcm, 0 cmcm) position? Give your answer using unit vectors. Express your answer in terms of the unit vectors i^i^i_unit, j^j^j_unit, and k^k^k_unit. Use the 'unit vector' button to denote unit vectors in your answer.

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
