Question

A particle (mass = 5.0 g, charge = 40 mC) moves in a region of space where the electric
field is uniform and is given by Ex = 2.5 N/C, Ey = Ez = 0. If the velocity of the particle at
t = 0 is given by vy = 50 m/s, vx = vz = 0, what is the speed of the particle at t = 2.0 s?

Answer 1

28m

Answer 2

A particle of mass 0.000137 g and charge21 mC moves in a region of space where the electric field is uniform and is 4.3 N/C in the x direction and zero in the y and z direction.If the initial velocity of the particle is given by vy= 1.3×105m/s,vx=vz= 0, what is the speed of the particle at 0.5 s?Answer in units of m/s.
