In a physics laboratory, there are two charged metal spheres placed on a horizontal table. One sphere has a positive charge of $+2.10 \mu C$ and is positioned at the origin ($0$ m) of the $x$-axis. The other sphere has a negative charge of $-4.70 \mu C$ and is located at $x = -1.00$ m along the $x$-axis. The lab technician wants to create a point on the $x$-axis where the net electric field is zero. To achieve this, they plan to place a third charged metal sphere at $x = +2.00$ m along the $x$-axis. What charge (in $\mu C$) should the third metal sphere have to ensure that the total electric field at the point $x = +1.00$ m is exactly zero? Assume that the charged spheres are small enough to be treated as point charges, and ignore any external electric fields or charges in the laboratory. Your Answer: Answer units
