Solve for Part C

(10%) Problem 10: A rod of length L 1.8 m lies along the y axis with one end at the origin. The rod carries a uniformly distributed charge of QI 4.8 puc. Apoint charge Q2 9.8 uc is located on the x-axis a distance a 1.7 m from the origin. dy Otheexpertta.com 20% Part (a) Consider a thin slice of the rod of thickness dy located a distance y away from the origin. What is the direction of the force on the point charge due to the charge on this thin slice? 20% Part (b) Choose the correct equation for x-component of the force on the point charge, dFx, due to the thin slice of the rod. Give your answers in terms of the variables Qi,Q2,L,a ,y,dy, and the Coulomb constant, k. Correct Answer t Answer Grade 100% dFe dFe Grade Detail Student Correct Feedback Final Answer Credit 100 Submission History Totals Hints Feedback dFe 0% 0% Totals A 20% Part (c) Integrate the equation for the x-component of the force from each slice over the length of the rod and calculate the x-component of the net force Fx in N.

Explanation / Answer

Part C)

by integrating the above equation we get

Fx = kQ1Q2/La ( y/(y^2+a^2)^0.5 ------------ limits of y from zero to L

therefore

Fx = kQ1Q2/a(L^2+a^2)^0.5

Fx = 0.249/2.4758

Fx = 0.1 N
