Question

8 small drops combine to form a big drop if the voltage of each drop is 10V then what is the voltage of big drop.

Answer 1

Explanation:

Given : 8Vtiny = Vbig 8 4/3 πr3 = 4/2 πR3 2r = R Vtiny = Kq/r Vbig = K ×8q/R Vbig = 8Kq/2r Vbig = 4Vtiny Vbig = 4 × 10 ⇒ 40 V Read more on Sarthaks.com - https://www.sarthaks.com/560579/eight-equals-charged-tiny-drops-combined-form-drop-potential-drop-then-potential-drop-will
