In millikan type appratus, the horizontal plate are 1.5 cm apart. with the electric field switched off an oil drop is observed to fall with the steady velocity 2.5×10^-2 cm/s . When the electric field is switched on the upper plate being positive, the drop just remains stationary when the p. d between plates is 1500v. Calculate the radius of the drop and how many electronic changes does it carry?
