question 74

Multiple Choice

Suppose you have two very sensitive balances that can measure the masses of individual particles,depicted below.In these figures,"p" corresponds to a proton,and "n" corresponds to a neutron. What is the relationship between the mass readings of the two balances? (Neglect differences due to experimental uncertainty.)

• A)The mass reading of balance 1 will be much higher than the mass reading of balance 2.
• B)The mass reading of balance 1 will be slightly higher than the mass reading of balance 2.
• C)The mass reading of balance 1 will be exactly the same as the mass reading of balance 2.
• D)The mass reading of balance 1 will be slightly lower than the mass reading of balance 2.
• E)The mass reading of balance 1 will be much lower than the mass reading of balance 2.
