A level physics capacitors

This question is about investigating the charging and discharging of capacitors.
Two students are given the circuit shown in Fig. 6.1. It consists of two resistors and two uncharged
capacitors, a 10V supply and a two-way switch S.
Resistors both 100k ohms, and capacitors in parallel both 100uF

(a) The first student is asked to investigate the charging of the capacitor C1 when S is connected
to A. She selects an ammeter of range 0 to 100μA reading to 2μA and a stopwatch reading
to 0.1s.
Discuss whether she has made a sensible choice of equipment for this experiment.

(b) The second student is asked to investigate the change of potential difference (voltage) V with
time t across each capacitor from the instant that S is moved from A to B.
(i) Explain why the final potential difference across each capacitor is 5.0V.
