Question

10. (10 points) If there is a potential of 10 volts at location B and a potential of 0 volts at location A. How much work would the electrical force producing the field do when moving a 10 coulomb point charge from point A to point B A. 100 J B. -100 J C. 10 J D. -10 J E. 0 J 11. (10 points) What is the electrical potential at the center of a dipole composed of two charges with absolute magnitudes of q seperated by a distance d A. 0 V D.-k 12. (10 points) Which of the following is not true of electrical potential A. It is a scalar field B. The potential energy of a given charge is linearly related to the electrical potential at the point in space in which it occupies C. The electrical potential is proportional to the electric field through the gradi- D. The work required to move a given charge is linearly related to the electrical E. The electrical potential is linearly related to the force on a charge at the given ent potential at the point in space in which it occupies point in space in which said charge occupies

Explanation / Answer

here,

10)

potential of point A , vA = 10 V

potential of point B , vB = 0 V

charge , Q = 10 C

the work done required , W = Q * ( vB - vA)

W = 10 * ( 0 -10) J

W = - 100 J

the work done required is - 100 J
