Pay it forward! Answer a questio1) For a positive point charge, the lines radiate ………. . While, for a negative point charge, the lines converge …………. .
2) The magnitude of the electric force between two protons is 2.3 X 10-26 N. Where ke = 9 X 109 N. m2/C, e = 1.6 X 10-19 C. How far apart are they? ………… m
3) The unit of the electric field is ………….
n while you wait for yours!

Explanation:

1) For a positive point charge, the lines radiate outwards

for a negative point charge, the lines converge inwards

2) F = 2.3 X 10^-26 N

k = 9 X 10^9 N.m²/C

q1 = q2 = e = 1.6 X 10^-19 C

r = ?

F = kq1q2/r²

r² = kq1q2/F

r = √[kq1q2/F ]

r = √0.0100

r = 0.10m

The two protons are 0.10 m apart

3) The unit if electric field intensity is Newton-per-coulomb N/C

does anyone know or what?
