Physics summer assignment vector multiplication

AI Thread Summary
To solve for the magnetic field vector (Vector B) in unit-vector notation, given the equation (Vector F) = q(Vector v) X (Vector B) with specified values, the user has derived an equation involving components of (Vector B). The relationship indicates that Bx equals By, simplifying the problem. The user is struggling to progress from the derived equation to isolate and determine the components of (Vector B). Assistance is requested as the assignment is due soon. The focus is on applying vector cross product principles to find the solution.

Homework Statement



In the product (Vector F) = q(Vector v) X (Vector B), take q = 2,
(Vector v) = 2.0i + 4.0j + 6.0k
(Vector F) = 4.0i - 20j + 12k

What than is (Vector B) in unit-vector notation if Bx = By

Homework Equations



dot and cross products

The Attempt at a Solution



4.0i - 20j + 12k = (8ybz - 12zby)i + (12zbx - 4xbz)j + (4xby - 8ybx)k

can anyone help? this is due tommorow =(. i really just don't know where to go from here at all
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
