Figure shows a nonconducting rod of length L = 5.5 cm has a nonuniform charge density λ = −2x. (a) Find the Potential at point P which is at a distance a = 10 cm from the rod. 4 (b) The electric potential at points in an xyz plane is given by V = (5.0 V/m2) x2y + (4.0 V/m4) y3z + (6.0 V/m3) yz2. In unit-vector notation, what is the electric field at the point (3.0 m, −2.0 m, 9 m) and the magnitude of the field? 4
