In your experiment, a charged ball of m= 100 g is suspended in place by a string at an angle theta from the y-axis (as shown in figure). A unform electric field is ponting to the right in the x-direction. Gravity acts down in the y-direction. In order for this situation to be possible in your experiment, what must the charge of the ball be?   a. positive b. negative c. neutral
