the mass of a proton is _times more than that of electron
Correct answer: A. 1836
- A. 1836
- B. 1829
- C. 1882
Explanation
The mass of a proton is 1836 times heavier than that of electron due to the strong nuclear force on the proton. Option B is incorrect since option A is correct. Option C is incorrect since option A is correct.

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.
