Not to sure what its asking i thought it was 2 but there ain't a 2

the answer is d. this is due to the fact a proton weighs 2000 times more then a electron

The correct option is (D) 2114 electrons

The positive charge on a proton is equal in magnitude to the negative charge on an electron. Protons and neutrons have approximately the same mass, but protons have much more massive than electrons which are approximately 2,000 times as massive as an electron. Because protons are so much heavier than electrons, the electrons do not make a significant contribution to the mass of an atom.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
