2 If the mass of a proton is 1-67X10-21
and the mass of an electron is all X10-343
Calculate the force
of
between
a protron and on election
ril two electrons
il two protrons
fake Ga 6:67X10" Nm2 kg distance
between the protrons
4.0m, distance
between the electrons = 2x 102m,
distance between the electrons ex 102m,
distance between the proton and the
electron -
5.4 x 10-11
m

Need asap ‼️ 20 pts which gravitational force field diagram is drawn correctly? (answers in pictures below)

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
