    How many 3x3 matrices can you find

    So working off of: A11x + A12y + A13z A21x + A22y + A23z A31x + A32y + A33z I should only be concerned with the first row? And in that first row I must somehow make it so it equals the desired result of xy? I feel like I've hit a brick wall on this problem. I do not understand how get...

    Spherical conductors connected by a wire.

    Homework Statement Two spherical conductors are connected by a long conducting wire, and a charge of 10.2 Micro-coulombs is placed in the combination. One sphere has a radius of 5.99 cm and the other has a radius of 7.99cm. What is the electric field near the surface of the smaller sphere...
