QUESTION 1 A small 12.00 g plastic ball is suspended by a string in a uniform, horizontal electric field. If the ball is in equilibrium when the string makes a 30 angle with the vertical, what is the net charge on the ball? Q = C QUESTION 2 Two charges q1 and q2 have a total charge of 10 C. When they are separated by 3 m, the force exerted by one charge on the other has a magnitude of 8 mN. Find q1 and q2 if (a) both are positive so that they repel each other, and q1 is the smaller of the two. (For the universal constant k use the value 8.99 109 N m2/C2. Attachments: PHYS-HW2.docx
