Which answer is correct? Question 1 Both William Crookes and J.J. Thomson struggled first to show that cathode rays were deflected by the electric field; this can be explained by the fact that A. without a low pressure gas, ionized gas molecules would create their individual electric fields that would decrease the net electric field. B. the cathode rays were too heavy to be deflected. C. they could not achieve enough magnitude of the electric field. D. there was a good vacuum in the chamber that prevented air drag. Question 2 The Millikan experiment was complicated by the fact that: A. the oil droplets were too light and hence accelerated too high velocities by the electric field. B. oil droplets were randomly charged. C. the viscosity of air was not known that time. D. the mass of the droplets could not be easily determined.
