Question

Complete The Table A charged particle is moving perpendicular to a magnetic field B. The table below shows the relationships between directions of three vector quantities. Notice that one entry is missing from each column of the table. Your job is to complete the table. Enter your answers in the pop-up menus below. Charge Velocity B-Field Force ty -z -x -Z -z ty Select the missing entry for the Velocity Column. Select the missing entry for the Force Column Select the missing entry for the B-Field Column.

Explanation / Answer

magnetic force F = q*(v x B)    q*[ cross product of v and B ]

for first row

Fb = +q*( vy j x -Bz k)

Fb = -q*vy*Bz ( j x k )

Fb = -q*vy*Bz ( i )

in second row

q is negative

-Fz k = -q*( -vxi x B )

-k = + (i x ?)

B is along -j -y axis

=========

in third row

Fy j = -q*( ? x -Bz k)

j = +(? x k)

? = -i = -x axis

missing entry for velocity column = -x

missing entry for Force column = -x

missing entry for B-Field column = -y
