The figure below shows a small, charged bead, with a charge of q = +44.0 nC, that moves a distance of d = 0.199 m from point A to point B in the presence of a uniform electric field 
E
 of magnitude 255 N/C, pointing right.
 
(a)
What is the magnitude (in N) and direction of the electric force on the bead?
magnitude Ndirection ---Select--- toward the right toward the left The magnitude is zero.
 
(b)
What is the work (in J) done on the bead by the electric force as it moves from A to B?
 
 
(c)
What is the change of the electric potential energy (in J) as the bead moves from A to B? (The system consists of the bead and all its surroundings.)

Step 1

Given:

Electric field, E = 255 N/C

q = +44.0 nC

d = 0.199 m

Step 2

(a) Calculating the magnitude and direction of electric force on the bead due to presence of electric field:

Magnitude of electric force can be calculated as follows: Electric force, F = qE Charge on the bead = +44 nC Magnitude of electric field = 255 N/C Hence, force, F (44x10-9x (255N/ C) 1.12x 10 N = F 1.12X10N Electric field is towards right and the charge on the bead is positive so, the direction of electric force on the bead would be towards right.

Work done can be calculated using the formula, W = Fdcos 0 As the force and the displacement both are towards right direction, hence value of cos0 1 So, work done, W= Fd Force acting on the bead = F = 1.12 x105 N Displacement of the bead 0.199 m Work done, W (1.12 x10 N) x(0.199m) 2.22x10J W 2.22 X10J
