Problem Set 8 1. Two similar charges of 250 statC are situated on small spheres 15.0 cm apart. What is the electric field intensity midway between the spheres? What is the potential at this point? zero (0) 66.67 statV 2. Two small metal spheres 25 cm apart have charges of 10 and 20 statC, respectively. Calculate (a) the electric field intensity and (b) the potential, at a point midway between them. 0.064 dyne/statC towards left 2.4 statV 3. Charge A of 5.0 puC situated 120 cm from a charge B of -3.0 uC. What is the potential at point C located at the midpoint between A and B? What is the potential of point D located 150 cm from A and 30 cm from B? How much work would be required to move a charge of 0.20 uC from D to C? 30,000 Vv, -60,000V; 18,000 J 4. Two equal charges of 5 x 107 C are 0.8 m apart. What is the electric potential at a point midway between the charges? 22,500V
