I NEED HELP ON THIS ASSIGNMNET i DONT KNOW HOW TO PUT THEM IN CODE PYTON Exercise 2. Explore the dipole. That is, place a positive charge at (1,0) and an equal but opposite charge at (-1,0) plot the resulting force vector at the (positively charged) target locations (-2,1), (-1,1), (0,1), (1,1), (2,1), (-2,0), (0,0), (2,0), (-2,-1), (-1,-1), (0,-1), (1,-1), (2,-1) - all on the same plot. Code this in the cell below.

CODE BELOW:

# find and plot the force of three (+) source charges on one (+) target charge

x_s = [-1, 0, 1] # x-coordinates of sources y_s = [0, 0, 0] # y-coordinates of sources

x_t, y_t = [-1, 1] # target coordinates

# let's assume all charges are single protons and # ignore the common factor k_e*q_t*q_s

for n in range(3): # place red o at each source plt.plot(x_s[n], y_s[n], 'ro', markersize=12)

plt.plot(x_t, y_t, 'ko', markersize=12) # place black o at target

Fvec = np.zeros(2,) # initialize the Force vector (Fvec)

for n in range(3): # build the Fvec, one charge at a time r = np.array([x_t-x_s[n], y_t-y_s[n]]) # r = r_t - r_s Fvec = Fvec + r/np.linalg.norm(r)**3 # Coulomb's Law Fvec = Fvec / np.linalg.norm(Fvec) # normalize for plotting purposes

plt.arrow(x_t,y_t,Fvec[0],Fvec[1],width = 0.06, length_includes_head = True)

plt.title('Figure 2',fontsize=18) plt.grid('on') plt.xlim([-2,2]) # extend axes to see arrow plt.ylim([-1, 2]);

The electrical force between two charged particles takes the exact same form as the gravitational force between two masses.

We suppose a source of charge (in coulombs, C) at position =(,) (in meters, m) and a target of charge (in coulombs, C) at position =(,) (in meters, m).

The force that the source charge imparts to the target charge is directed along the line through the two charges. The source will repell the target if they have the same sign and will attract the target if they have opposite sign. We use python to visualize the scene, and the arrowhead implies that repells .
