Question

QUESTION 6

1. The absolute potential at a distance of 2.0 m from a negative point charge is -100 V. What is the absolute potential 4.0 m away from the same point charge? (Page Ref: Sec. 17.5) -25 V -50 V -200 V -400 V
   

2. QUESTION 9

   1. A 5.0-nC charge is at (0, 0) and a -2.0-nC charge is at (3.0 m, 0). If the potential is taken to be zero at infinity, what is the electric potential at point (0, 4.0 m)? (Page Ref: Sec. 17.5 Unit 2-Part 3) 15 V 3.6 V 11 V 7.7 V
      
      

      QUESTION 13

      1. A 15-microF capacitor is connected to a 50-V battery and becomes fully charged. The battery is removed and a slab of dielectric that completely fills the space between the plates is inserted. If the dielectric has a dielectric constant of 5.0, what is the capacitance of the capacitor after the slab is inserted? (Page Ref: Sec. 17.7-17.9) 75 microF 20 microF 3.0 microF 1.0 microF
