A proton (q = 1.60 x 10-1º C, m= 1.67 x 10-2" kg) move in a uniform magnetic field B = 0.500 Tî . At t = 0 the proton has velocity components v = 1.50 x 10° m/s, Vy = 0, and v; = 2.00 x 10° m/s. In addition to the magnetic field there is a uniform electric field in the negative x- direction, Ē = (-3.00×10ʻ V/m)î . (a) Describe the path of the proton. Does the electric field affect the radius of the helix? Explain. (b) At t= T/2, where T is the period of the circular motion of the proton, what is the x-component of the displacement of the proton from its posițion at t = Q?

Question

please answer #8, the answer is already given below i just need the computation 

8. A proton (q =1.60 x 10-19 C, m= 1.67 x 10-27 kg) move in a uniform magnetic field B = 0.500TÎ . At t = 0 the proton has velocity components v, = 1.50 x 10' m/s, Vy = 0, and v; = 2.00 x 10° m/s. In addition to the magnetic field there is a uniform electric field in the negative x- direction, E = (-3.00×10ʻV/m)î. (a) Describe the path of the proton. Does the electric field affect the radius of the helix? Explain. (b) At t = T/2, where T is the period of the circular motion of the proton, what is the x-component of the displacement of the proton from its position at t = 0?
