Asked in ETEA MDCAT 2012 2012Moderate

According to Millikan's oil drop experiment, the charge on an oil droplet is:

Correct answer: D. All of the above

  • A. Quantized
  • B. Integral multiple of 'e'
  • C. Not less than 'e'
  • D. All of the above

Explanation

Millikan's oil drop experiment demonstrated that the charge on an oil droplet is quantized, meaning it can only exist in discrete values, which are integral multiples of the elementary charge 'e' (1.6 × 10-19 C). Therefore, the charge cannot be less than 'e', and it is always an integer multiple of 'e'. Each of these statements is a valid description of the charge characteristics, making all options collectively correct. The correct answer is indeed 'All of the above'.

About Discovery of the Proton

The discovery of the proton follows the study of positive rays, also called canal rays, observed in discharge tubes and later identified as positively charged particles. The work of Goldstein and Rutherford is linked to the proton's charge, relative mass and role in the nuclear model, distinct from the discovery of the electron.
