ANSWER ALL 3 QUESTIONS **CORRECTLY** AND YOU GET 5 STARS

A uniformly charged ring of radius 10.0 cm has a total charge of 47.0 pC. Find the electric field on the axis of the ring at the following distances from the center of the ring. charges are located on a circular arc as shown in the figure below. (Take r = 3.92 cm. Let to the right be the +x direction and up along the screen be the +y direction.) (a) What is the total electric field at P, the center of the arc? (b) Find the electric force that would be exerted on a 4.63-nC point charge placed at P. Three charged particles are located at the corners of an equilateral triangle as shown in the figure below (let q = 1.60 mu C, and L = 0.750 m). Calculate the total electric force on the 7.00-mu C charge,

Explanation / Answer

Q1.

a) for x =1 cm (<R), E = k*Q*x / r^3

=> E = ((8.99 x 10^9 Nm
