Calculate the magnitude of the electric field at the center of a square 42.5 cm on a side if one corner is occupied by a -38.2 uC charge and the other three are occupied by -27.4 uC charges Express your answer to three significant figures and include the appropriate units. ​

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
