Two equal positive point charges q1=q2=2.0 microC are located at x=0, y=0.30 m and x=0, y=-0.30 m., respectively. What are the magnitude and the direction of the total (net) electric force that these charges exert on a third point charge Q=4.0 microC at x= 0.40 m, y=0?
a.) Draw the location of the charges in a coordinate system. Label the position and charges.
b.) Draw the direction of forces on Q due to q1 and q2.
c.) What is the force exerted by q1 on Q (F1q)?
d.) What is the force exerted by q2 on Q (F2q)?
e.) What are the magnitude and direction of the net force of q1 and q2 on Q? Draw the net force on the free-body diagram of charge Q.
