The electric field at the midpoint between q1 and q3 is given by:
E = (1/4πε_0) * [(q1/r^2) + (q3/r^2)]
where r is the distance between q1 and q3.
In this case, r = 1m, q1 = -1uC, and q3 = -3uC.
Therefore, the electric field at the midpoint between q1 and q3 is:
E = (1/4πε_0) * [(-1uC/1m^2) + (-3uC/1m^2)]
E = (1/4πε_0) * (-4uC/1m^2)
E = -1/(4πε_0) * 4uC/m^2
E = -1N/C
The direction of the electric field is from q3 to q1.
Three negative charges -1uC,-2uC and -3uC are placed at the corners of equilateral triangle. If the length of each side is 1m, find the magnitude and direction of electric field bisecting the line between the charge q1 and q3.
