DATA The electric potential in a region that is within 2.00 m of the origin of a rectangular coordinate system is given by V = Ax i + By m + Cz n + D , where A , B , C , D , l , m , and n are constants. The units of A , B , C , and D are such that if x , y , and z are in meters, then V is in volts. You measure V and each component of the electric field at four points and obtain these results: (a) Use the data in the table to calculate A , B , C , D , l , m , and n . (b) What are V and the magnitude of E at the points (0, 0, 0), (0.50 m, 0.50 m. 0.50 m), and (1.00 m, 1.00 m, 1.00 m)?

Calculate the integral (v) = f vƒ (v)dv. The function f(v) describing the actual distribution of molecular speeds is called the Maxwell-Boltzmann distribution,
=
ƒ(v) = 4π (· v²e-mv²/2kT
