Question

Please write clearly and show all steps or I will not give a thumbs up for your answer! If I can’t read and understand the answer it won’t help (: thanks!

uicuiate the electric force that acts on each ion. THE ELECTRIC FIELD .A point charge of 4.0 puC is a: the origin. What are the 37 magnitude and direction of the electric field on the x axis at (a) = 6.0 m and (b) x =-10 m? (c) Sketch the function Er versus x for both positive and negative values of x. (Remember that E, is negative when E points in the-x direction)

Answer 1

answer)a) we know the formula for electric field is given by

E=kq/r²...............1)

k=8.99*10⁹Nm²/C²

here r=6m

so now using the eqn 1 we have

E=8.99*10⁹* 4*10^-6m/(6m)²=999 N/C

so the answer is 999N/C or 1000 N/C ( if they want the answer is kN/C then 1kN/C )

and direction is +x direction since the answer is positive

b) again using the eqn 1

here r=-10m

so E=8.99*10⁹*4*10^-6m/(-10m)²=-360N/C

since the answer is negative so direction is -x direction

so the answer is 360 N/C ( if they want the answer in kN/C then  0.36kN/C and don't put the negative sign in the answer because they only want the magnitude)

c) the graph is given below

5601, ー250 2 2 x(m)
