(a) Write down an expression for the electric potential caused by a point charge. Define any terms you use with the aid of a diagram (3 marks) (b) A very large non-conducting flat plate has areal charge density (o = -12 Cm²). Using Gauss' law and stating your approximations, show that the electric field close to the plate is given by E2-0/280, and calculate this value for the plate. (4 marks)
