Two point charges q1 = 2 C and q2 = - 5 C are located in the (x,y) plane at coordinates (2,0) m and (-3,0) m respectively. Find:
a) The electric field created for both charges at points (0,0), (5,0) and (0,2).
b) the electric force on a point charge of -2.00 C placed at points (0,0), (5,0) and (0,2).
