Answer:
D
Step-by-step explanation:
The mass of the proton has an exponential of -27 and the electron has -31.
Negative 27 is larger than negative 31 so you know the proton is larger than the electron in mass.
9.1 divided by 1.7 is approiximately 5.
Those exponents are 4 digits apart. 31 - 27 = 4 so there are 4 zeroes added onto the 5.
So the proton is about 50,000 times bigger than the electron in mass.
