Question

In an oil drop experiment, charged oil drops of mass m and charge q are released at a height h, one at
a time, at intervals ∆t >
square root
2h/g. The drops are collected in a large metal sphere of radius R with a
small opening at the top. The total number of drops that are able to enter the sphere will be

Answer 1

ouaoy!!!!!! nice problem!!!!

Answer 2

Yep it's a good problem

Answer 3

ok
Δt is given so we ignore any next drop will working with the rpevius

Answer 4

Yeah no drops will be at the same point at a time

Answer 5

even more
drop drops due to its weight
1st drop has only W
2nd drop has W AND an electrical appauling force from sfaire now charged q
3 drop W and electrical from 2q

Answer 6

do you see

Answer 7

Oh yeah the metal is a conductor so charge will be accumulated at the surface

Answer 8

exactly!!!!!

Answer 9

Yep got it thanx
