A particle with a charge of q = -5.00 nC is moving in a uniform magnetic field of B with sole component B; = -1.26 T. The magnetic force on the particle is measured to be F with sole component F = -7.60x10-7 N. %3D Part B Calculate vz, the x component of the velocity of the particle.

Please help with parts B and C

. A uniform electric field E and a uniform magnetic field B are present in some region. A particle with positive charge q and mass m moves with speed v to the right. a. What do the directions of the electric field and magnetic field need to be in order for the particle to move with constant speed? Ignore gravity, air resistance and any other non-electromagnetic forces. b. Find the ratio E/B in order for the particle to move at constant speed.

In the xyz coordinate system, specify (in terms of the unit vectors ˆx, ŷ, and ˆz) the direction of the magnetic force on each of the moving particles shown in the figure. Note: The positive y-axis is to the right; the positive z-axis is towards the top of the page and the positive x-axis is directed away from the page 1. What is the direction of the magnetic force in figure c?:     a. The magnetic force is directed down the screen. (z negative)     b. The magnetic force is directed up the screen. (z positive)     c. The magnetic force is directed towards the inside of the screen. (x negative)     d. The magnetic force is directed away from the screen. (positive x)     e.The magnetic force is directed to the right of the screen. (and positive) 2. What is the direction of the magnetic force in figure a?     a. The magnetic force is directed down the screen. (z negative)     b. The magnetic force is directed up the screen. (z positive)     c. The magnetic force is directed towards the…
