1. Up3. Right5. Into page0. No direction/zero 2. Down4. Left6. Out of page P a) A magnetic field pointing out of the page in a region of space is shown (for example, created by a solenoid). The magnetic field is decreasing in strength. What direction is the accompanying electric field at the point P ? b) An electric field pointing out of the page in a region of space is shown (for example, created by the parallel plates of a capacitor). The electric field is decreasing in strength. What direction is the accompanying magnetic field at the point P ?
