A is 25cm away from B. Point C is 10cm away from point B. What is the electric field at C? All points are in a line A--B-C.
Would this work?
Find the electric fields a pont A & B. Then add the two fields ? Or would you subtract the two fields ?
Use the formula [tex]{E} = k\frac{Q}{r^2}[/tex]
Is the field on point A & B going left or right?
By Reasoning does the electric field at A have to be bigger that B, since A is further away, Or should B be bigger that A , or is there no way of telling, just by looking at the question
