Im getting an error in python, "File "Untitled", line 17 s.velocity = s.velocity +((1.6e-22)cos(wt)*dt) ValueError: operands could not be broadcast together with shapes (3) (0) "
The code is posted below. does anybody know how i can fix this?
B = vector(0,0,0.5e-4) # Tesla, the earth's magnetic field
q = -1.6e-19 # Coulomb, the charge on an electron
m = .00507 # kg, the mass of an electron
s = sphere(radius=2.0e-6)
s.velocity = vector(100,0,0) # m/s
w=(2*pi,0,0)
trail=curve(color=color.blue,pos=s.pos)
s.pos=(0,0,0)
t=0
dt=1e-10 # s
while t < 3e-6:
if s.pos.x < 1e-6:
s.velocity = s.velocity +((1.6e-22)*cos(w*t)*dt)
trail.append(s.pos)
t = t+dt
rate(4e-7/dt)
else:
s.acceleration = q*cross(s.velocity,B)/m
s.velocity = s.velocity + s.acceleration*dt
s.pos = s.pos + s.velocity*dt
trail.append(s.pos)
t = t+dt
rate(4e-7/dt)
