Answer 1

Let the charge on each capacitor be $q$
thus the potential against each capacitor will be
$(q$ is in micro coulomb $)$
across $C_{1}$ capacitor $= q / 20 V$
across $C_{2}$ capacitor $= q / 40 V$
across $C_{3}$ capacitor $= q / 50 V$

as we can see for same charge on each capacitor as they connected in series, the capacitor $C_{1}$
has maximum potential drop, which according to the situation can be $50 V$
so $q / 20 = 50$
so $q = 1000$ micro coulomb
so the potential drop against $C_{2}$ capacitor $= 1000 / 40 = 25$ volts
while the potential drop against $C_{3}$ capacitor will be $1000 / 50 = 20$ volts
hence as all the capacitors are in series so the potential difference across $X$ and $Y$
$= 50 + 25 + 20 = 95$ volts

Answer 2

Let the charge on each capacitor be

q

thus the potential against each capacitor will be

(q

is in micro coulomb

)

across

C_{1}

capacitor

= q / 20 V

across

C_{2}

capacitor

= q / 40 V

across

C_{3}

capacitor

= q / 50 V

as we can see for same charge on each capacitor as they connected in series, the capacitor

C_{1}

has maximum potential drop, which according to the situation can be

50 V

so

q / 20 = 50

so

q = 1000

micro coulomb

so the potential drop against

C_{2}

capacitor

= 1000 / 40 = 25

volts

while the potential drop against

C_{3}

capacitor will be

1000 / 50 = 20

volts

hence as all the capacitors are in series so the potential difference across

X

and

Y

= 50 + 25 + 20 = 95

volts
