Thirty microcoulombs of NEGATIVE charge experiences an electrostatic force of 27. mN. What is the magnitude and direction of the electric field?
What will be an ideal response?
Question 2
Consider the x-axis with 4.0 C at x = 1.0 meter and -2.0 C at the origin. Where should 6.0 C be placed so that the net force on it is zero?
What will be an ideal response?
