Define electric field intensity​

Electric field intensity is a Vector Field. Electric field intensity (E, N/C or V/m) is a vector field that quantifies the force experienced by a charged particle due to the influence of charge not associated with that particle

Explanation:

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
