Question

which of the following is inversely proportional to the force between two electric point charges?

A. the square of the distance between them
B. the magnitude o f Charge 1
C. the magnitude of Charge 2
D. the distance between them

Answer 1

hint:
applying the Coulomb's law, we can write:
\[\Large {r^2}F = K{Q_1}{Q_2}\]

Answer 2

ok! what do we plug in?

Answer 3

we have to study the form of that expression only!

Answer 4

ohh okay! what does that mean for this problem? :/

Answer 5

that expression means the square of the distance and the force F are inversely proportional each other

Answer 6

ohhh so choice A?

Answer 7

yes! correct!

Answer 8

yay!! okay last one!!:)

Answer 9

ok!
