Question

Hiiiiii
If a drop has a capacitance of 5microF then find the capacitance of a droped formed by 64 such drops.

Answer 1

Heya......✋
Answer is in attachment......

Answer 2

Capacitance for drop => R/k

where R is the radii.From Volume conservation,

Vnet = 64V

R^3= 64r^3

R = 4r

For big drop,
C = R/k.......(1)

For small dop,

5 = r/k........(2)

Divdng the both eq.

we get,

C = 5*(R/r)

=> 5*4 = 20 mF.
