The nearest star to our Sun is Alpha Centauri, which is about 4.4 light-years away. Assume that it too has an Oort cloud about 1.6 light-years in diameter. How many solar systems can fit between us and it

c.the charges if the proton and electron and gravity

pe = weightxheight = 2000x1000=2,000,000joules

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.
