the conducting plate is charged to a potential of 4,000volt. a second metal plate , charged to a potential of 1,000 volt is brought near the first plate at a distance of 10cm. what is the field intensity at any point between the plates?
If an earthed plate is brought near a positively charged plate, the potential and capacity of charged plate respectively:
The potential difference between the two plates of a parallel plate condenser is 250 volt and the distance between them is 5 cm. The uniform electric field intensity is:
