https session masteringphysics.com/myct/temview?assignment UlUU Phy 284 Sp 17 p003 Practice Problem 17 3 Practice Problem 17.3 Now let's apply law and the principle to calculate the force on point charge due to the presence of other nearby charges. Two point charges are located on the positive ar axis of a coordinate system. Charge qh 3.0 nC is 2.0 from the origin, and charge -8.0 4,0 cm from the cm force (magnitude origin. What is the total charge and direction) exerted by these two charges on a third point 5-0 located at the origin? Figure 1 diagram of the situation aby Free-body diagram for q, ProDisplay P222va SOLUTION and F2 for ga charges repe know their re SOLVE We u find the result Both Fi and Since Feneala REFLECT Bee lahl Part A Prac In the sam Express yExplanation / Answer
1] F = kq3*[q1/r1^2 + q2/r2^2] = 9e9*5e-9*[3e-9/0.02^2 - 8e-9/0.04^2]
= 0.0001125 N - x direction answer
2] F = 9e9*3e-9*[5e-9/0.02^2 + 8e-9/0.02^2]
= 0.000878 N answer
+ x direction
