Apoint charge is used to determine the electric field around a charged particle. why is it necessary that the point charge does not affect the position of the charge being tested? a) the amount of charge will increase if the charged particle moves closer to the point charge, so any change in position changes the field. b) the amount of charge will decrease if the charged particle moves closer to the point charge, so any change in position changes the field. c) electric fields are inversely proportional to the square of the distance, so any change in position changes the field. d) electric fields are directly proportional to distance, so any change in position changes the field.

An infinite plane of charge occupies the x − y plane with surface charge density σ = −1.8 × 10−6c/m2 . an infinite line charge with charge density λ = 2.2 × 10−6c/m runs parallel to the y axis through the point (20.0cm)ˆz. a negative point charge, q = −8.3×10−7c, is located at the point (10.0cm)ˆz. consider the electric field at a point p at (20.0cm, 0.00, 20.0cm). you must show the symbolic formula you use before substitution and place appropriate english description in the solution to this problem. do not even consider reporting an electric field that is not a vector or a number without appropriate units. (a)draw the electric field vectors of the three objects at point p and label them e~ plane,p , e~ line,p , and e~ point,p for the electric field of the plane, line, and point charge respectively. get the directions correct, you have no way to figure out relative magnitudes. (b)compute the electric field of the plane at point p, e~ plane,p . (c)compute the electric field of the line charge at point p, e~ line,p . (d)compute the electric field of the point charge at point p, e~ point,p . (e)compute the total electric field at point p, e~ p .

1.) three point charges are positioned as follows: a positive charge +q is located o tid.a the point (b,0. a negative charge is located on the xais at the point (2b,0. positive point charge+q/3 is located at the point ( 2 3b-1/3b) what is the symtom for the electric field at the origin due to this system of point charges, in terms (express any numerical values with three significant figures) at the x-axis and the third, a g and b? carefully consider and draw in three electric field vectors originating from the origin: the what information do contribution to the net electric field from cach of the three source charges. you need to find the x and y-components of each of these three vectors (a) what is the electric field at the origin due to only the +q charge at position (1)? (b) what is the electric field at the origin due to both the +q charge at position (i) -2q charge at position (2)? = 1+2 (c) what is the electric field at the origin due to only the +q/3 charge at position (3)? (d) what is the symbolic expression for the electric field at the origin due to this system of point charges, in terms of k,, q and b? (e) what is the tangent of the angle s that e makes with the negative x-axis? (draw a new picture! ) tan φ= (f) what is the magnitude of the electric field at the origin if b-3.00 cm and q = 1.00 nc? (n/c) (g) if a fourth positive charge +q is placed at the origin, what is the magnitude of the force on that charge? how does this magnitude change if the fourth charge is a negative charge -g? how does the direction of the force on the fourth charge change if charge +q versus -q is placed at the origin?
