Question

Will give medal! Please help.

How do the magnitude and charge of the two charged particles in the figure compare?

a. same magnitude and both have a positive charge.
b. a is positive, b is negative and b has half the magnitude of a.
c. a is positive and b is negative with the same magnitude.
d. same magnitude and both have a negative charge.

Answer 1

@eashmore please help?

Answer 2

@Vincent-Lyon.Fr Could you help? :(

Answer 3

What is your choice?

Answer 4

Personally, I'm thinking c...

Answer 5

Possibly D.

Answer 6

I just really need a second opinion.

Answer 7

How is the field around a positive charge?
How is the field around a negative charge?

Answer 8

The electric field from a positive charge points away from the charge while the field from a negative charge points towards the charge.

Answer 9

So it really can only be 'a' right?

Answer 10

Answer 11

@eashmore sorry if I seem impatient... :(

Answer 12

@ash2326 ?

Answer 13

It can only be 'a' because the field lines point away from both particles.

But understand that the charges are also equal in magnitude. That's why the field lines are symmetric.

Oh I see! Thank you so much!!
