11. A particle with positive charge q = 3.20 x 1019 C moves with a velocity v= (2 i + 3 j - k) m/s through a region where both a uniform magnetic field and a uniform electric field exist. a) Calculate the total force on the moving particle (in unit-vector notation), taking B = (2 i + j+ k) T and E = (-4 i – j– 2 k) V/m. b) What angle does the force vector make with positive x axis?

A proton (charge +e, mass mp), a deuteron (charge +e, mass 2mp), and an alpha particle (charge +2e, mass 4mp) are accelerated from rest through a common potential difference V. Each of the particles enters a uniform magnetic field B, with its velocity in a direction perpendicular to B. The proton moves in a circular path of radius p. In terms of p, determine (a) the radius rd of the circular orbit for the deuteron and (b) the radius r for the alpha particle.
