Chapter 26, Problem 1PLA

Electric field lines are drawn (a) from positive charges to negative charges; (b) from negative charges to positive charges; (c) from the largest charge to the smallest charge; (d) from the smallest charge to the largest charge.

Expert Solution & Answer
Check Mark
To determine

The direction of electric field lines.

Answer to Problem 1PLA

Option (a) from positive charges to negative charges.

Explanation of Solution

Electric field lines are an imaginary lines that always starts from the positive charge and end at the negative charge. And the number of electric field lines is directly proportional to the total number of charge.

Conclusion:

  1. (a) The electric field lines always starts from positive charges and end at negative charges. Thus, option (a) is correct.
  2. (b) The electric field lines always starts from positive charges and end at negative charges. Thus, option (b) is incorrect.
  3. (c) The direction of electric field lines does not depend on the size of the charge. Thus, option (c) is incorrect.
  4. (d) The direction of electric field lines does not depend on the size of the charge. Thus, option (d) is incorrect.

(a) Red blood cells often become charged and can be treated as point charges. Healthy red blood cells are negatively charged, but unhealthy cells (due to the presence of a bacteria, for example) can become positively charged. In the figure, three red blood cells are oriented such that they are located on the corners of an equilateral triangle. The red blood cell charges are  A = 2.20 pC, B = 7.50 pC,  and  C = −4.40 pC.  Given these charges, what would the magnitude and direction of the electric field be at cell A? (1 pC = 1 ✕ 10−12 C.)     magnitude     direction
Two point charges are placed on the x axis as shown in (Figure 1). The first charge. q₁ = 8.00 nC, is placed a distance 16.0 m from the origin along the positive x axis; the second charge. q2 = 6.00 nC, is placed a distance 9.00 m from the origin along the negative x axis.
