In a Millikan-type experiment, two horizontal charges plates are 2.5 cm apart. A latex sphere of 1.3x10^-15 kg remains stationary between the plates when the potential difference between the plates is 400 V. The upper plate is charged positive and the lower plate is negative. What is the type of charge on the sphere? And what is the electric field intensity between the plates?
