**Homework Statement**

Two charges -1nC and +1nC are positioned at (-2,0) and (2,0) respectively, where distances are in cm.

a) Sketch 5-6 field lines E in the region bounded by x=-2, x=2, y=0 and y=8

b) Caclculate the horizontal and verticle components of the E field at (-2,6), Draw a diagram showing the charges, the fields at P due to both charges and the resultant field. Find magnitude E and the angle phi (measured from the +x-axis)

**The attempt at a solution**

b) I'm not sure how to calculate the hotizontal and ver components of the E at (-2,6)!
