Two charged metal plates (8 m wide by 12 m high) are placed parallel to each other and are separated by 2 cm of vacuum (kvacuum = 1) as in the diagram below A helium nucleus (charge +3.2x10-19 C) is placed 1 cm to the left of plate B as shown in the diagram. The helium nucleus experiences an electric force of 2 x 1014 N to the left ie. towards plate A. What is the magnitude of the voltage between the plates and which plate is at the higher voltage? A B 12m 8 m 2 cm Select the closest answer: O 1656 V and Plate B is at the higher voltage. O 1250 V and Plate A is at the higher voltage. O 2540 V and Plate B is at the higher voltage. 256 V and Plate A is at the higher voltage. O 1250 V and Plate B is at the higher voltage.
