1Two parallel metal plates, a distance of 2mm apart, have a potential difference of 1000V across them.
What is the electric field strength between the plates?- AA 500 V.m^–1
- BB 50000 V.m^–1
- CC 50000 N.C^–1
- DD 500000 N.C^–1
2An oil droplet has charge –q and is situated between two horizontal metal plates as shown in the diagram.
The separation of the plates is d. The droplet is observed to be stationary when the upper plate is at potential +V and the lower plate is at potential –V.
For this to occur, what is the weight of the droplet?
- AA Vq/d
- BB 2Vq/d
- CC Vd/q
- DD 2Vd/q
3A positive charge and a negative charge of equal magnitude are placed a short distance apart.
