Question

Figure below gives the electric potential Vas function of x. In which region is the x-component of the electric field is zero? V 1 2 3 4 5 In regions 1.3 and 5 In regions 2 and 4 In region 3 only. In region 5 only. QUESTION 10 Two spherical conductors of radil, 8.00 cm and ) 4.00 cm are separated by a distance much greater than the radius of either sphere. The spheres are connected by a conducting wire as shown in the figure. The charges on the spheres in equilibrium are q, and respectively, and they are uniformly charged. If the charge on sphere 24. - 6.00 nC, what is the charge q, on sphere 1 and what is the potential of the two spheres? 91 9. = 93.8 nC V = 42.2 kV 9:- 1.50 nC V = 169 V 9. - 12.0 nC V = 1.35 kV

Answer 1

# Electric field is given by dv Ex= - dx Exao =) dv = V = Constant dx N is constant in region & 3. & 5. So In region 13.45. G & C₂ to let the capacitanus of spheres are same say V. in equilibrium potential will be Q = GV = Unto riv UITG 8₂ V Q = CV Unto riv or ñ UITG & V 2 -> fem nem inc lane 9x109 x 12x 10 8x162 $ UIT Gori V= 1.35 x 10 v V = 1.35 kV
