1. An electric field is given by Ex =3.5x3 kN/C. Find the potential differencebetween the points on the x axis at x = 1 m andx = 3 m.
..... kV
---------------------------------
2. (a) Find the maximum net charge that can be placed on aspherical conductor of radius 12 cm before dielectric breakdown ofthe air occurs.
.... µC
(b) What is the potential of the sphere when it carries thismaximum charge?
..... kV
-------------------------------
3. Consider an electron and a proton that are initially at restand are separated by 1.20 nm. Neglecting any motion of the muchmore massive proton.
(a) What is the minimum kinetic energy with which the electronmust be projected so it reaches a point a distance of 26.0 nm fromthe proton? Assume the electron's velocity is directed radiallyaway from the proton.
..... J
(b) What is the electron's speed at this energy?
..... m/s
