Suppose the charge on the inner conducting sphere is +3 µC, while +4 µC of charge is deposited on the conducting shell. (a)Find the surface charge (in µC) on the inner surface of the shell.

(b)Find the surface charge (in µC) on the outer surface of the shell

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].

The electric potential a distance r from a small charge is proportional to what power of the distance from the charge? a. r^-1 b. r c. r^-2 d. r^2
