A long line carrying a uniform linear charge density +50. 0μc/m runs parallel to and 10. 0cm from the surface of a large, flat plastic sheet that has a uniform surface charge density of −100μc/m^2 on one side. Find the location of all points where an a particle would feel no force due to this arrangement of charged objects.

I’m not sure about this question

Umm, its not your fault, and its because some things in your brain.

The scientist was trying to demonstrate that humans can introduce their own biases into an experiment. bias is a prejudice in favor of one thing compared with the another.in this case, the bias is believing that mice with higher intelligence would solve the maze better.  bias in science should be avoided as it is not desirable that research becomes influenced by scientists personal beliefs.
