Remember to include units & to mind your significant figures! You may find it helpful to draw a diagram, but this is not required.

3. In Fig. 2, what must the values of q1,2 be to have an electric potential of zero at point P? Hint: there are likely to be a 92 mathematical set of such values that satisfy this condition that describe how the value of the charges compare to h each other (i.e., their ratio). 91 O P Fig. 2. Fixed distribution of point charges q, 2 on the surface of a cylinder. Point P is located at the center of the base
