Question

Point charge g 5.00 nC s at the origin and point charge q2 +3.00nC is on the z -axis at r 3. cm. Point P is on the y axis at y 4.00cm. previous l 6 of 9 l next Part A calculate the electric fields E 1 and E at point P due to the charges a and a2. Express your results in terms of unit vectors (see example 21.6 in the textbook). Express your answer in terms of the unit vectors 2, J. Enter your answers separated by a comma E1, E. N/C Submit My Answers Give Up incorrect; one attempt remaining; Part B Use the results of part (a) to obtain the resultant field at P, expressed in unit vector form. Express your answer in terms of the unit vectors i, j N/C Submit My Answers Give Up

Explanation / Answer

q1 = -5 nC, q2 = 3 nC

Electric filed E = kq/r^2

E1 = - (9*10^9*5*10^-9)/(0.04^2) j

E1 = -28125 N/C

cos(theta) = 3/5 , sin(theta) = 4/5

r2 = (3^2+4^2)^0.5 = 5 cm

E2 = -(9*10^9*3*10^-9*(3/5)/0.05^2)i + (9*10^9*3*10^-9*(4/5)/0.05^2) j

E2 = -6480 i +8640 j
