How does the electric force between two charged particles change if the distance between them is decreased by a factor of 3?

0.19 m/s and 0.45 m/s

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
