Question

A small sphere with mass 5*10^-7 kg and charge is released from rest a distance of 0.500 m above a large horizontal insulating sheet of charge that has uniform surface charge density = 8*10^-12 C/m^2 .

Using energy methods, calculate the speed of the sphere when it is 0.150 m above the sheet of charge?

Answer 1

In your problem where the ask is to calculate the sped of the sphere when it is 0.150m above the sheet where as the small sphere has a mass of 5*10^-7 kg and the charge is release from  a rest distance of 0.5m. The answer to this problem would be 0.0127
