Electrostatic Potential And Capacitance

The charge will have resultant pull upwards along equatorial line

Let II capacitors of each be connected in series in a row and m such rows be connected in parallel.
As the voltage needed in the arrangement is 1000 V , so, potential difference across each capacitor can have 250 V across it.
Therefore, number of capacitors in each row,
Equivalent capacitance of each row
or
Equivalent capacitance of the circuit,

Minimum number of capacitors required

Mass of each charged particle =
