Consider a region with a uniform electric eld E directed to the right and a uniform Magnetic field directed upwards. [In this problem there is no gravity} a) A positivelyr charged ball enters the region, and travels through it in a straight line. Which way is the ball moving For this to be possible\"? (3 marks) b} As the ball moves through the region, a gust of wind slows the ball down, how does the ball move now. [2 marks] (c) Describe how it is possible to create a uniform electric field, and give a real life example. {2 marks} (d) A negativelyr charged ball is now sent through the region moving straight into the page with the same speed that the positive ball had initially. What happens to the electron? {3 marks}
