If the electric field is zero everywhere in a region, then the potential is -Sel

Question

If the electric field is zero everywhere in a region, then the potential is -Select everywhere in that region. The map shows equipotential lines, with north to the top as usual, If you walked eastward (to the right on the map) from the red dot, would you go uphill or downhill O uphill Odownhill O neither What setting should you use on the meter? ohms O AC volts O DC volts O AC amps A brick sits on the top of a hill with a gravitational potential energy of 147 J. To determine the gravitational potential of the brick, we would also need to know which one of the following? The location of zero gravitational potential. 0 The height of the hil. The mass of the brick The value of g on the planet.

Explanation / Answer

1. If E is zero then the potential is constant everywhere.

2. Neither

3. AC Volts

4. We need the mass of the block.
