Answer to Question #185404 in Field Theory for Ameerah

Question

Math / Physics Problem Solver

A negatively charged droplet of mass 4.5x10 -3ng remains balanced in the electric field between parallel horizontal plates which are 10mm apart if the potentional difference between the plates is 1000 V calculate the charge on the droplet (g =9.8 -2)

Answer 1

Answer

Using formula

$Charge=\frac{Mgd}{V}\\=\frac{4.5\times10^{15}\times9.8\times0.010}{1000}\\=44.1\times10^{10}C$
