asked • 03/15/21# Calculate the horizontal component of the net force, in newtons, on the charge which lies at the lower left corner of the rectangle.

Four point charges of equal magnitude *Q* = ** 55** nC are placed on the corners of a rectangle of sides

*D*

_{1}=

**cm and**

*21**D*

_{2}=

**cm. The charges on the left side of the rectangle are positive while the charges on the right side of the rectangle are negative. Use a coordinate system where the positive**

*11**y*direction is up and the positive

*x*direction is to the right.

I get 1.10 * 10^-3 as the answer but its wrong so please show your work so I understand where i went wrong!
