The capacitance of a capacitor is 10 μF. The distance between the plates is made half and area is doubled. The capacitance of the capacitor will now be:

i think its 20 im not sure tho

No. Capacitance is proportional to A/d.
A doubles and d is reduced by half.
Both changes have the effect of doubling the capacitance.

Try again.

What happens when you double something twice?
