Question

Consider two charges, q_1 located at the origin and q_2 located a distance d to the right of the origin as shown below. If q_1 q_2 in which region (i, ii, or iii) is the electric field zero? If q_1 and q_2 are equal in magnitude and opposite in sign in which region (i, ii, or iii) is the electric field zero? Charge q_1 = 2 mu C and q_2 = - 4 mu C, in which region (i, ii, or iii) is the electric field zero d) Charge q_1 = 2 mu C and q_2 = 4 mu C are separated by 10cm. What is the magnitude and direction of the electric field at x = 5cm? Identical point charges are fixed to the opposite corners of a square. Where does a third point charge experience the greater force, at one of the empty corners or at the center of the square? Explain your answer.

Explanation / Answer

6.

a) II

b) None of the three regions

c) I

d)(8.99*10^9*2*10^-6*30)/.1^2 = 5394000

7. The force atempty corner is

           F = [F12+F22]

     The force at center of thesquare isZero

So the force at the empty corner is greater
