Question

39 points 1 Pravious Anawers M4 13.5 04 My At a particular moment, three cherged perticles are located as shown in the figure below. 91-60, Q2-7.0 c, and 3-8.5 IC. Your answers to the following questions should be vectors.(Recall that 1 c-1 × 10-6 c. Aseme that the +x axis is to the rign, the + y axis is up along the page and the +z axis points into the page. Express your answers in vector norm) (a) Find the electric feld at the location of Qs, due to Q1 ful X NC (b) Find the electric field at the location of Qs, due to Q2 -

Explanation / Answer

a) E1 = k*Q1/r1^2

= 9*10^9*6*10^-6/0.05^2

= 2.16*10^7 N/c

in vector notation,

E1 = <-2.16*10^7*4/5 , 2.16*10^7*3/5 >

= < -1.73*10^7, 1.3*10^7 > N/c <<<<<<------Answer

b)

E2 = k*Q1/r2^2

= 9*10^9*7*10^-6/0.03^2

= 7.0*10^7 N/c

in vector notation,

E2 = < 0, -7.0*10^7 > N/c <<<<<<------Answer

c)

Enet = E1 + E2

= < -1.73*10^7, -5.3*10^7 > N/C <<<<<<------Answer

D) Fnet,3 = Q3*Enet

= -8.5*10^-6 < < -1.73*10^7, -5.3*10^7 >

= < 147, 451 > N <<<<<<------Answer
