Question

Two charges of the same magnitude and opposite signs (q1=4 nC = -q2) are separated by a distance 2d, where d = 4 cm. Determine the resultant electric force that acts on a charge q3 = 7 nC when it is at point

(a)What is the resultant electric force on q3 if it is at point A;

F₃= [( )i + ( )j] x 10^{( )}= N

(b)What is the resultant electric force on q3 if it is at point B;

F₃= [( )i + ( )j] x 10^{( )} = N

(c)What is the resultant electric force on q3 if it is at point C;

F₃= [( )i + ( )j] x 10^{( )} = N

and (d)What is the resultant electric force on q3 if it is at point D.

F₃= [( )i + ( )j] x 10^{( )} = N
