blems 18-8, 007 10.0 points The magnitude of a uniform electric field be- tween the two plates is about 2 x 105 N/C. k set If the distance between these plates is These 0.1 em, find the potential difference bet ween nd/or the plates. ot be Answer in units of V efore 008 10.0 points s willTwo charges are located along the r-axis. One blems has a charge of 6.3 C, and the second has a charge of-3.5 ?(. If the eleetrical potential energy associ- ated with the pair of charges is 0.038 J. celerwhat is the distance between the charges? rence The value of the Coulomb constant is 8.98756 x 109 NÂ·m2/C2 and the acceleration due to gravity is 9.sI m/s Answer in mits of Solution 7) For parallel plates, V = E * d where V is the potential difference, d is the separation, and E is the electric field V = 2e5 * 1e-3 V = 200 volts 8) We know that potential energy for system of two charges is given as U = kq1q2 / r where r is the distance between two charges , k is coulomb\'s constant - 0.038 = 8.98756e9*6.3e-6*-3.5e-6 / r r = -8.98756e9*6.3e-6*-3.5e-6 / - 0.038 r = 5.215 m .
