G = 6.674 X 10-11 Nm2/kg?
1. If you and your friend both have a mass of 50kg and are sitting 3m away from
each other, what is the gravitational force between the two of you?
2. What is the mass of another student sitting 5m away from you if your mass is
50kg and there is a gravitational force between the two of you of 1.62 x 10-6N?
3.
If another student in the room has a mass of 70kg and your mass is 50kg and the
gravitational force between the two of you is 2.7 x 10-8 N, how far are they sitting
from you?

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
