Explanation / Answer

1)

F13 = k*q1*q3/d^2

= 9*10^9*7.5*10^-6*3.9*10^-6/0.099^2

= 26.86 N

F23 = k*q2*q3/d^2

= 9*10^9*3.3*10^-6*3.9*10^-6/0.099^2

= 11.82 N

F3,x = F13*cos(60) + F23*cos(60)

= (26.86 + 11.82)*cos(60)

= 19.34 N <<<<<<<<<--------------Answer

b)

F3,y = F13*sin(60) - F23*sin(60)

= (26.86 - 11.82)*sin(60)

= 13.02 N   <<<<<<<<<--------------Answer
