Shouldn't the x component be the current? And how do we solve for the angle if we don;t know the y component?

Homework Statement A person decides to swim across a river 84m wide that has a current moving with a velocity of 0.40m/s[E]. The person swims 0.70m/s[N] relative to the water. In what direction should she swim if she lands at a point directly north of her starting position? Note: This is part...

But the answer is

I'm confused about the wording of the question. Usually we use a positive test charge along with the given charge. Is the test charge applying the force on q? Then it would be to the right of q since the force is directed to the left. And then q would move to the right as it is attracted by the...

My teacher said you're not supposed to plug in - signs into the equations for fields because it implies direction, so we only use magnitudes

Ok, and how do you find the direction?

I did, but I don't know how to find the direction

Homework Statement An electric field with a magnitude of 2.5N directed to the left, acts on a negative charge of -5.0C. Determine the electric field in which the charge is located. Give. FE=2.5N q=-5.0CHomework Equations FE[/B]=qε The Attempt at a Solution ε[/B]=2.5N/5.0C=0.5N/C. I don't...

The first part of the question, which I didn't post because I already figured it out, said that the system was in static equilibrium

Thanks!

Homework Statement Is it possible to introduce local charge on a conductor? Homework Equations - The Attempt at a Solution I know that electrons can move freely from atom to atom in the conductor, so if you introduce excess electrons to the conductor, they'll spread out and there won't be a...

OH, ok. thanks!

But if you know Fnet and you know Friction=μFn and the only 2 forces in the x component are friction and tension, then they should be equal and you should be able to do algebra to solve for tension

Homework Statement If you decelerate in one direction, are you accelerating in the opposite direction? Ex. You are standing in an elevator and are slowing down, going upwards- are you accelerating downwards since you're decelerating in the opposite direction, upwards? Homework Equations -...

How would there even be a friction force if there;s no rope? The only reason there's static friction is because there is an attempted motion because of the force of tension from the rope
