Displayed below are six statements about electric and magnetic fields and forces, three of which are true and three of which are false. Check the three boxes beside the three statements that are true. OA. The electric force acting on a stationary point charge due to a second charge depends on the velocity of the second charge. O 8. Gauss's law is true for charged particles travelling at speeds close to the speed of light. OC. If the charge distribution in a region of space is known, then the electric field can be caliculated. OD. The magnetic field produced by a small current loop falls off as 1 at large distances from the loop. O E. When a magnetic field is applied perpendicular to a strip of semiconducting material that is carrying a current, positive and negative charge carriers are deflected towards the same side of the strip. O F. For two short current elements A and B, the force on A due to the current in B is of equal magnitude but opposite in direction to the force on 8 due to the current in A.
