Physics - Vectors Problem. :/?
In the product F(vector)= Qv(vector) x B(vector), take Q=5,
v(vector) = 2.0i + 4.0j + 6.0k and F(vector) = 270i -300j + 110k.
What then is B(vector) in unit-vector notation if Bx = By?
(i believe the x in the initial equation is cross product, not multiplication.)

i____J_____k____i____J
2------4---------6------2------4
270---(-300)--110---270---(-300)
4(110)i+6(270)j+2(-300)k
-270(4)k-6(-300)i -2(110)j
which simplifies into
440i+1620j-600k-1080k+1800i-220j
added together, we have
2240i+1400j-1680k
and now for simplifying:
224i+140j-168k ->
112i+70j-84k ->
56i+35j-42k
_______
/8i+5j-6k/
-----------
you're welcome.
keep on with those steps: a million. comedian strip a image. 2. set up a coordinate equipment. Which way is x valuable? Which way is y valuable? 3. comedian strip all forces appearing on the elephant. be valuable you get your angles marvelous. 4. ruin your tension vectors into their x and y-factors. it is complete by trigonometry. If this step is confusing reference the vectors area of your textbook. 5. Sum up all the forces interior the x-path making valuable to coach valuable and unfavorable warning signs in keeping with which path the forces are pointing. Set the sum of those forces equivalent to m*a_x and sparkling up. Do the comparable for the y path. in case you carry on with those steps faithfully, all tension issues grow to be a splash cake.
