Question

the potential of a large liquid drop when 8 liquid are combined is 20volt. then the potential of each drop was?​

Answer 1

Answer:

The correct answer is 10 V

Explanation:

Volume of 8 drops = Volume of big drop

∴ (4/3πr^3) × 8 = 4/3πR^3

⇒2r=R....(i)

According to charge conservation

8q=Q....(ii)

We have

V∝ 1/r

or V1/V2 = r2/n

⇒20/V2 = 2 r / r

⇒V2=10 V
