Question: In a Millikan type experiment, two horizontal plates are separated by a distance of 2.5 cm, and the upper plate is positive. The voltage

In a Millikan type experiment, two horizontal plates are separated by a distance of 2.5 cm, and the upper plate is positive. The voltage to the plates is adjusted so that a 1.5 x 10-15 kg sphere remains stationary. a. Draw a free-body diagram showing the forces acting on the charged sphere q. Label the force vectors with appropriate symbols identifying the forces involved. b. Is the sphere charged negatively or positively? c. If the electric field intensity is 1.84 x 104 N/C, what must be the charge on the sphere? d. How many elementary charges does this correspond to? e. If the electric field is turned off, and the charged sphere begins to fall, what will its velocity be after a time of 1.0 ms? Assume that air resistance over this short time is negligible.
