Question

a. Determine the work in joules required to move a charge of 20 Coulombs through a potential of 24 volts?

b. Find the electric field in N/C, if a force of 4 N is required to move a charge of 20 Coulombs?

c. Which of the following statements are true or false?

Electric field lines are everywhere perpendicular to the equipotential lines

An equipotential line is the locus of a set of points all of which have the same potential

The electrical force is never zero along an equipotential line

The direction of an elec field at any point is the direction of the force on a positive charge at that point

Please show work for a & b

According to the given problem,

a)The work required to move a charge q through a potential V is,

W = qV = 20*24

W = 480 J

b)Using the fallowing relation,

E = F/q

E = 4/20

E = 0.2 N/C

c) Ans:

Electric field lines are everywhere perpendicular to the equipotential lines - True

An equipotential line is the locus of a set of points all of which have the same potential - True.

The electrical force is never zero along an equipotential line - False

The direction of an elec field at any point is the direction of the force on a positive charge at that point - True

I hope you understood the problem, If yes rate me! or else comment for a better solution.
