ok thanks. so specifically in relation to that question, they are talking about a 3-dimensional plane correct? (up) being the 3rd dimention or axis, (north) being the 2nd, and (east) for example being the 1st?
ok thank you for your advice. so if the B field points "up" do you think that if we had a x y z co ordinate system, up would refer to the positive z direction and north would be the positive y direction?
sorry it's definitely 0.0200 T.
so if the B field is in the same direction as the velocity of the electron...why are they even asking the question and why is there an follow-up part b to the question? I really don't understand this question. like conceptually i get it but i don't think it's...
Homework Statement
A magnetic field of 0.0200 T (up) is created in a region
a. Find the initial magnetic force on an electron initially moved at 5.00 x 10^6 m/s [N] in the field
b. What is the radius of the circular path? Make a sketch showing the path of the electron.
Homework Equations...
so i went wrong in that i subtracted
$$|\Delta \vec{v}| = \sqrt{(\Delta v_{x})^2 - (\Delta v_{y})^2}$$
instead of adding
$$|\Delta \vec{v}| = \sqrt{(\Delta v_{x})^2 + (\Delta v_{y})^2}$$?
Well there's a vector for velocity of the ball after its hit. 52 m/s w20n so that would tell me that the impulse needs a direction to it. Perhaps Fnet as well.
Homework Statement
A baseball with a mass of 0.125 kg is moving horizontally at 32.0 m/s [E], when it is stuck by a bat for 0.00200 seconds. The velocity of the ball just after the collision is 52.0 m/s [W 20 N].
Homework Equations
p = m Δv
Fnet = ∆p/∆t
there are also these...
