Answer:
a). The resulting potential difference across each capacitor is 1.8 kV.
(b). The energy lost is zero.
Explanation:
Given that,
First capacitor = 160 pF
Second capacitor = 640 pF
Voltage = 1.8 kV
(a). We need to calculate the initial charge
Using formula of charge
Put the value into the formula
We need to calculate the final charge
Using formula of charge
The total charge is
We need to calculate the resulting potential difference across each capacitor
Using formula of potential difference
Put the value into the formula
(b). We need to calculate the energy lost when the connections are made
Using formula of energy
Put the value into the formula
Hence, (a). The resulting potential difference across each capacitor is 1.8 kV.
(b). The energy lost is zero.
