Problem: The figure(Figure 1) shows three charges at the corners of a square.Write the electric field at point P in component form. Assume that x-axis is horizontal and points to the right, and the y-axis points upward.Express your answer in terms of the variables Q, L, unit vectors i^, j^, and appropriate constants.

FREE Expert Solution

The electric field at a point is given by:

E=kqr2, where is Coulomb's constant, q is charge., and r is the distance from the point to the charge. 

The electric field at point P due to charge 1 (-Q).

E1x=k(-Q)L2
