1.2.1. A positive point charge ? is placed on the −?-axis at ? = −?, and a negative point charge −? is placed on the +?-axis at ? = ?. A positive point charge ? is located at some point on the +?-axis. (a) In a free-body diagram, show the forces that act on the charge ?. (b) Find the ?- and ?-components of the net force that the two charges ? and −? exert on ?. (Your answer should involve only ?, ?, ?, ? and the coordinate ? of the third charge.) (c) What is the net force on the charge ? when it is at the origin (? = 0)? (d) Graph the ?-component of the net force on the charge ? as a function of ? for values of ? between −4? and +4?.

answer:b) ?? = 2?? ??? (? 2 + ? 2 ) 3/2 , ?? = 0 c) 2?? ?? ? 2

find the answer include a diagram if needed , thanks alot! ^^
