Question 1 d)
Two insulating handles are now used to pull the (10.0 cm diameter) electrodes away from each other until they are 1.0 cm apart. The electrodes remain connected to the 15 V battery during this process.
What is the charge on each electrode?
Give your answer to 0 decimal places in nC. Write your answer without units i.e., 12.6 nC as 12.6.
Question 1 c)

A storm cloud has -25 nC built up in a 1.0 km diameter spherical charge centre located 10 km above the ground. This charge centre attracts a similar amount of positive charge that is spread on the ground below the ground. The charge centre and ground act as a charged capacitor, with a potential difference of V. In a lightning strike, the large electric field between these two charged regions (acting as electrodes) may ionise the air resulting in a conducting path between the cloud and ground, through which the 'capacitor' discharges.

Question 2d)
A storm cloud has -25 nC built up in a 1.0 km diameter spherical charge centre located 10 km above the ground. This charge centre attracts a similar amount of positive charge that is spread on the ground below the ground. The charge centre and ground act as a charged capacitor, with a potential difference of V. In a lightning strike, the large electric field between these two charged regions (acting as electrodes) may ionise the air resulting in a conducting path between the cloud and ground, through which the 'capacitor' discharges.
If 12.5 C of charge is transferred from the cloud to the ground in a lightning strike, what fraction of the stored energy is dissipated?
