.\ a) Determine the magnitude and direction of the electric field at a point in the\ middle of the middle of two-point charges.\ b) Determine the magnitude and direction.\ We set a

0.2\\\\mu C

charge in nearby of point charge

q

so that the charge

q

exerts a force\ of

5\\\\times 10^(-5)N

to it. Determine the electric field that this unknown charge q produces?\ As seen in the illustration below, an equilateral triangle has three-point\ charges at each of its corners. Determine the electric field at a position on\ the

x

-axes that is midpoint between the two charges.

4. Two-point charges of 2C and 1.2C are separated by 2cm. a) Determine the magnitude and direction of the electric field at a point in the middle of the middle of two-point charges. b) Determine the magnitude and direction. 5. We set a 0.2C charge in nearby of point charge q so that the charge q exerts a force of 5105N to it. Determine the electric field that this unknown charge q produces? 6. As seen in the illustration below, an equilateral triangle has three-point charges at each of its corners. Determine the electric field at a position on the x-axes that is midpoint between the two charges
