Question

Four point charges are at the corners of a square of side a as shown in the figure below. Determine the magnitude and direction of the resultant electric force on q, with ke, q, and a left in symbolic form. (B = 4.5q and C = 2.5q. Let the +x-axis be pointing to the right.)? a.) F=______. b.) direction ______degrees counterclockwise from the +x-axis  

Four point charges are at the corners of a square of side a as shown in the figure below. Determine the magnitude and direction of the resultant electric force on q, with ke, q, and a left in symbolic form. (B = 4.5q and C = 2.5q. Let the +x-axis be pointing to the right.)? a.) F= . b.) direction degrees counterclockwise from the +x-axis

Explanation / Answer

Ke= 9*10^9

no along line joining two B since force are opposite directions and equal magnitude in that line

so force on q will be along the line joing C and q

Force = 9*10^9 * 2.5*q*q/(2*a*a) 11.25*10^6 *q*q/(a*a)
