Acharge of 5 µc is on the y axis at y = 7 cm, and a second charge of -5 µc is on the y axis at y = -7 cm. find the force on a charge of 2 µc on the x axis at x = 3 cm.

The force on X Fx=0 N

The force on Y Fy=-2.18 N

Explanation:

We have an array of charges, we will use the coulomb's formula to solve this:

but we first have to find the distance and the angule of the charge respect the charges on the Y axis:

we can notice that it is the same distance from both charges on Y axis.

we can find the angle with:

for the charge of 5µC

for the charge of -5µC

the net force on the X axis will be:

and

So the net force on X will be Zero.

for the force on Y we have:

and

Fy=

So the net force on Y is Fy=-2.18N

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
